Exactly, you just need an HDMI over Wireless module. These are mass produced for the filmmaker and video production industry. I don't see a pcb sized wireless hdmi transmitter, but there are small DC consumer ones as cheap as $100 which could be broken out of their plastic enclosures and repackaged within the handheld. At such a short range, no way you need to have a giant antenna on the transmitter either. There's also a video on Youtube of someone creating a diy wireless transmitter, however it is an analog RCA signal.As for the controller, hopefully the controller buttons could be transmitted over Bluetooth, by existing solutions. Lots of options there. There is also a diy guide on Adafruit.
