Upgrading a government in 1.2

[Pezlu]

First of all, hi everybody; I'm back after a long time... I was active around 2006, if I remember correctly, when EB 1.2 was yet to come :P
In the meantime I switched to linux, so I had some trouble with most games... until I decided to give RTW (and more importantly, EB) a try. With a few workarounds, it's perfectly playable! Just a few minor things don't work as expected, but you know... WHO CARES! I can still enjoy EB :P

Now on the real question: back when I played, in level 5 regional MICs you could recruit mercenary generals in every province. Now, with the revamp of the client ruler system, you just need a level 4 government to recruit them... and that's quite nice.
Now, I've built a couple level 4 governments in provinces where I wouldn't, to trigger the carthaginian reforms. I'm building the MICs in the meantime.
According to the recruitment viewer, the highest level of regional MIC with recruitable units in this provinces is 4, except for mercenary generals who are now recruitable via the government building. In my old games, if I wanted to upgrade the goverment from level 4 to level 3 (like I will do in these provinces) without "cheating", I had to tear down the regional MIC as well and rebuild it up to level 4, so level 5 units wouldn't be recruitable anymore. Quite expensive and boring, if you ask me...
But now, since level 5 MIC does not add any more units in those region's roster, having a level 4 or 5 regional MIC is actually the same, right? If so, I just have to destroy the government building and build a level 3 in its place.

If I do that, and I leave the client ruler there, will I have problems with traits or something else? I think I'll just wait he dies of old age anyway, but I prefer to know, just in case.

Actually, I think this is a fairly straightforward issue (I can upgrade the government with no problems whatsoever, and maybe the client ruler gets a bad trait... but I just can move him out of the way), but still, I prefer to be sure... and this is also an excuse to come back to the forums :P

Thanks!
