Well I am currently building all my civs into modular format for BtS i am just over half way, However Romania is by far the largest of all the civs to convert and will be my last project I undertake. I can tell you that I will be continuing the EDU for Romania and expanding on it a little my hope is to have it done in the next 2 weeks however that depends on work commitments, and how long it takes to convert my last four civs before I tackle Romania, (Currently I am working on overhauling the Getai to bring it into line with the rest of my EBCIV factions) So we will see how we go.
As for new UUs I cant say I'm completely against new UUs however to give the Romanians more than one UU would give them a decided advantage in the industrial and modern ages, when compared with the other "vanilla" civs in the game.
