It would be impossible* to make the game work in anything other than the current perspective (or possibly isometric) so really you’re just talking about a fancier tileset with some extra graphical features.
Although this sounds like a good idea, it would take way too much time away from anyone who had the coding skills to actually help. I’d say that if the core game is good enough (think DF) I’m sure someone will come along with some extra graphical tools.
*From a gameplay standpoint, a lot would be ruined and even looking past, on the technical side you’d pretty much have to remake the entire game to get it working (so much so it’d be a different game)
