But yeah, let's ignore years of lore.
So, on that subject, I've been reading up on Sarna on some mechs on the list in this topic, to refresh my memory, and guess what I've run into
Enforcer ENF-4R said:
The Enforcer's biggest flaw though was its limited ammunition stores, though when possible a truck-and-crane reloading system is used during less-mobile battles. Attempts were made to replace the small laser with another ton of ammunition, however there were complicated linkage problems in getting the ammo from the left torso to the right arm, increasing the rate of jamming or reducing the rate of fire to unacceptable levels. What's more the rounds had to be routed along the 'Mechs back where its armor was weakest.
If making changes to a mech is supposed to be as easy to make as you propose, then how come something seemingly as trivial as taking out a small laser and adding a ton of ammo was too difficult to acomplish?
Let's find some more, shall we?
Kintaro KTO-19 said:
However, the left-arm system, where the Holly-5 and one of the HoverTec-6 launchers are located, is extremely complex, requiring the entire arm to lock in place for three seconds while reloads stored in the torso cycle through. Sudden movements can cause the SRM system to jam, which usually requires an hour to clear before it is usable again, although jams for the LRM launcher are very rare. As yet the reason for this difference in performance between the two systems has not been determined.
Ah, Battlemech technology at it's finest. A system so complicated that it locks up entire arm in place during a reloading cycle, and can cause jams of the SRM but not LRM. Why? Who knows, it goes unfixed. Not sure about you but I wouldn't risk asking my techs mucking with something like that for fear of breaking the system completely.
Shadow Hawk SHD-2H said:
Lang Industries had technically introduced the Shadow Hawk many years prior to 2550, but this version of the 'Mech suffered from a debilitating fault in its armor plating. The line was recalled and a major overhaul was accomplished in 2550 without any difficulties which solved the issue for most (but not all) Shadow Hawk models.
Catapult CPLT-C1 said:
The original Anderson 21 model jump jets tended to break down over prolonged use, venting into the machine's interior and overheating the 'Mech. A general recall in 2566 to replace the 21s with improved Anderson 25s solved the issue, though some Catapults never received this retrofit.
Again, if making modifications to mechs is supposed to be easy, why do mass recalls of those mechs? Wouldn't it be cheaper and faster for the producer to make retrofit packages and send them to owners of mechs, let their techs carry the retrofit?
Speaking of jury-rigging things:
Clanbusters entry said:
When the Battle of Tukayyid was arranged, the upgrades were purposefully designed as field refits that were quick and easy to apply within a few months with ComStar's resources at the time.
ComStar, which at the time was still most technologically equipped part of IS had "quick" refit packages... that took
months to apply. We're not ComStar. We'll have neither resources nor the tech-savvy they had, nor proper installations.

That's just things I spotted going through entries on Sarna. I'm sure someone bored enough could go through TRO's and dig out more examples like this. Bottom line: BattleMechs aren't easily modifiable. Never were supposed to be. Ease of modification is Omnimech thing, if BattleMechs were easy to change up then Omnis wouldn't be consider such a technological jump. The fact that we are getting even the hardpoint-based customization ability is already a concession in favor of gameplay as it is.
