I only know that Krastorio 2 makes more advanced armor.
That should be OK then. Armor just gives a bonus to characters' main inventory size, but vanilla armors (modular and power armor) do that as well, so that should already be taken care of.
And I understand that you are planning a new update?
Yes, a big one, with a fresh GUI and support for mods that change properties of a character that are not related to looks (e.g. Jetpack or Bob's Classes). I've submitted a patch to Bob, and he said he'd look at it -- but as he hasn't much time to spend on modding at the moment, he didn't implement it yet. But I guess I should upload in the next few weeks, whether he's ready or not, just to get the mod out so it can be tested in real games. :-)
