Impossible 9th gen combination?

Before I pull the trigger on a board, is there one that can work out this combo?

I'm working out the spec list for my first hackintosh. I'm having a tough time finding a motherboard that will support a 9th gen intel (e.g., core i9 9900k or i7 9700) and is matx/micro atx and uses z370. The risks of z390 seem a bit too high for me. Obviously, there are alterations I can make if need be. I'm not planning to overclock so I may downgrade my chip. Another obvious change is to move to an atx board.

Thanks,
