Okay, so I wrote a second post, to reply to some of the latest stuff (and combining them would've made one ... huge wall of text)
Keep a copy of the 1.04 landed_titles.txt (and whatever other files may define de jure kingdoms, haven't really looked into modding in CK2) to overwrite the 1.05 one, in addition to changing the 1 value for time to change de jure? Should do the trick...
I'm thinking more "less centralised and established state", same as for France, and most/every other (Christian?) Kingdom, as a stereotype of the early middle ages, actually. I doubt the HRE will really implode even with these changes.
Regarding the hodgepodge - unlikely even with these games. At the very least, people always spray around the word "always" WAY too liberally in these sort of discussions. I've seen a Kingdom of Finland rule Norway, Finland and England though (Hardrada won, conquered Finland, and moved his Capital to Uusimaa for some reason - yay for Helsinki!), so anything is possible of course. Regarding reasons to go on crusade, how about gaining an entire new Kingdom that way? Not to mention the current incentives of piety, prestige, the crusader trait, and church opinions during the crusade - and after, due to the trait. And under the new system the most likely scenario for Aquitaine (the kingdom of which may be named/modded to be Occitania, so that concern is utterly trivial) indeed should be that either it forms early, or it gets assimilated into France anyway.
This is what the real-life medieval de jure system pushed by the Papacy was. The in-game system is a game mechanic meant to help in moving the game forward in a plausible manner (for some value of plausible), that draws inspiration from the real-life de jure system. In my opinion, not even only from that, but also from the legal customs in use in said area etc., but I don't think we have any "Word of God" (=Dev) comments on this.
This is an ironic example to me, since to me it just says that the law is different in different de jure kingdoms, which is also in the game. Nothing about the Papacy attempting to encourage peaces within Christian Kingdoms.
The problem I see with changing the change in De Jure from 100 to 400 years is that, like that, we would never get rid of the fantasy Kingdoms (like Bavaria, Frisia and Aquitania) that would be present from the start of the game, I'm afraid... the AI would be able to create them right until the end of the game.
Unless there is a way to eliminate those Kingdoms altogether, while also giving their De Jure provinces to the correct Kingdoms, of course.

The problem is that people keep having in their minds the concept of the HRE as the weak and divided state that arouse from the Thirty Years War. That was not the previously the case. Has anybody actually noticed that the HRE always remained in existance, regardless of internal problems? Can anbody even quote ONE example of an "implosion" that utterly wrecked the HRE? I was a far more stable entity than what players, only thinking of the Empire of latter centuries, can bring themselves to admit.

I don't want the HRE to always turn into a hodgepodge of petty Germanic Kingdoms that would never, ever, be concievable, nor do I want to have NO reason whatsoever to go on a Crusade because I can conquer things and turn them into my De Jure land right in the heart of Western Christendom.
Or to see the rise of a Kingdom of Aquitania whose lords were never interested in (if anything could have been tried, would be the creation of a Kingdom of Occitania, and that right at the start of the game).

Fact is, you didn't read anything I wrote before and still have *no idea* of what the De Jure system was. Like I said multiple times, it was meant to crystallize Kingdoms in Western Christendom, exactly to force Catholic rulers to seek new Crowns in the lands of the heathens/infidels. Thus enabling the Crusades.

A example on how monarchies take the issue seriously can be seen in the UK: has anyone noticed that Scotland, even today, isn't De Jure part of England? If you sign a contract in Scotland today and later want it annulled, don't go to London for it - the courts there will say it was made under Scottish Law and that they, being English, have no jurisdiction over it, they only handle English Law. You have to handle contracts done in De Jure Scotland in Scotland, you can't deal with that in De Jure England.
This is an ironic example to me, since to me it just says that the law is different in different de jure kingdoms, which is also in the game. Nothing about the Papacy attempting to encourage peaces within Christian Kingdoms.
