This is what I ended up doing. Works well, got it working both with standalone Dolphin and through Retroarch easily, and it even has this fun mouse mode that is cool for my living room PC (but that I still rarely use).
With direct Bluetooth I did get it working fine in Dolphin, but the Bluetooth range on the wireless chip was so poor that it was unreliable from my couch.
