Naval improvements

Back in the old days I recall a mod for RTR called 'Naval Mod' or something,)
Just out of curiosity I wonder if such option would be included for EB2 as well. I did some historical researches and factions like KH, Kart, Ptolemoi and even SPQR/Empire latter in the game should have abilities to build more buildings improving their naval trade and income.
The best way to achieve it would be to improve existing ones imo.
I have some ideas but first and foremost I need to know if the game engine itself allowes such add-on's???

buildings are almost entirely moddable. We can add new levels (up to a maximum of 9 per building complex). We can change the bonuses given by specific levels, including what they recruit.

Thx Foot this is good news although I haven't thought about recruitment of any units(they are accurate so far) but to add more flexibility of income cominig via naval import/export of goods. After I finish sorting out things I have in mind I'll try to post them and you can use them if you find them any good to EB2

Great news, Foot!
