Porting such engine(s) makes only sense if there are enough games using it and if they are OpenSource.

Sure some people scream I will make a game, but to be honest there are only a few people in the community capable of coding a 3D game from scratch even using such engine.

We had alot of donated stuff in the past that is dusting and never was really used.

I am not against porting such thing at all. It should just taken into account what the user gets from it at the end. One or Two games that maybe will ported sometime in the future is not something I would invest in.

Better set a fixed goal like the engine and two games. So everyone spending money can know what to expect as result.
