With how the system is set up at the moment, where class is basically meaningless because of massive unbalance issues and homebrew gimmicks it wouldn't contribute much. They would have to start making an actual D&D game first and forget about the whole DOS reskins.
Solasta is the poor man's Pathfinder atm and this is still DOS3.
I'm actually waiting for Realms-Beyond. If I remember correctly it's suppose to come with a mod tool as well, looking forward to it.
