@Slagar,
1. As I remember, they do
2. It doesn't affect autoresolve, I never touched those tables and Idk it it's possible to tweak balance there
3. There is no such version, because I had to hide matchlock towers behind lvl 4 castle update and it would've sucked not being able to build lvl 4 forts long into the game, after you conquered almost all of Japan

Great idea, in fact the best mod regarding tower defence overhaul I have come across.
1. Do the archery towers change for the sengoku/rots campaigns aswell ? (I think so but wanted to be sure)
2. Do the increased stats of the tower defences/star fort cannons get accounted for when auto resolving assaults ? (I guess not bc I cant imagine how you would manage that)
3. Would it be possible to get a version that doesnt decrease the research time for Gunpowder Mastery? In my opinion this makes matchlock units available to early
