Excellent question, unfortunately I'm not too clear either.
Tangentially related, I managed to get primogeniture succession working for merchant republics! It requires some working in \common\laws\succession_laws.txt. First step is obvious: change the code of
This step alone makes the default succession primogeniture when you pick a merchant republic to start the game as (Pisa in 1066, for my testing). There's some tooltip weirdness, because the kingdom still says another patrician is the expected successor, but it does in fact get passed onto your oldest son.
If that's all you do, though, then as soon as you die, you'll get a game over. This is because, despite your successor holding the merchant republic titles and having a
Thus, the second required step is to edit
Presto!
Still some tooltip weirdness, like I said, and the F4 succession window shows the expected patrician successors, but the actual successor is your oldest son, and is listed as such for your family palace and some of the title (and he inherits all the titles despite the tooltips not always matching up with that).
I assume that, instead of doing the above two steps, you could just edit

merchant_republic_government
, there's one title he didn't inherit: the family palace, which was still set to Seniority and went to your oldest dynasty member. Not having a family palace is what disqualifies you from playing a government in the republic_governments
group, rather than not having merchant_republic_government
per se.Thus, the second required step is to edit
succ_seniority
in a similar manner to succ_primogeniture
, but in reverse, making sure that a merchant republic does not qualify for it.Presto!

I assume that, instead of doing the above two steps, you could just edit
succ_seniority
alone, to make it so that a merchant republic can have it, thus your heir there matches your family palace heir.
