If it were me, I'd do one or two oversized knobs that overlap the edge of the pickguard a bit.

I'm really digging this, and love the knob placement!
No lipstick pups for me tho... The blade hummers look good - my immediate thought was 2 Dimension style hummers.
Definitely go ahead with this body shape though and post the progress!!
