Play as romulans with green interface
 

I have not yet searched if it has been suggested before, but I guess it's pretty obvious:

Play as romulans with a green interface.

I don't think it's currently possible ? But hopefully in the future.

When I was a young kid I kinda like those green ships, they look badass.

And they could cloack.

All players should get 1 extra free character slot to play as romulans.

So 3 slots in total: 1 fed, 1 klingon, 1 romulan.
