The main controller you’re looking for is the Hasu controller. It seems to be out of stock though so sourcing it might be hard. That replaces the mini usb with usb c and gives you QMK support. I think you do have to file the housing a bit since usb C is wider than mini usb
As for wireless, I’m not too sure of a ready made solution but you could look into using a nice!nano if you’re up for some tricky testing/wiring; that supports wireless over BLE
