Although not exactly what you're looking for, I use an HHKB with my right hand when I play.
I've grown accustomed to just using [Fn+toprowkeys] for all my function keys. Ignoring the spectator commands, the only important things I even leave up there are the scoreboard, pause, and console.
For regular computer usage, the only thing that bugs me with these 60% boards sometimes is the lack of a numpad.
