I'm not really sure where to ask this. But would it ever be possible to create our own themes one day? I'm an artist and, although I am going to be happily making maps soon, I think it'd be really great to be able to make custom themes and tiles in the future. Not necessarily new units entirely (that's wishful thinking), but just the ability to modelswap/design unique tiles and structures. Even if it was limited to a per map basis, it'd be pretty neat.

If i'd be better off asking this elsewhere, let me know; it's something i'd like to know the answer to
