Same ol', same ol'.
Well, yeah, you could do that pretty easily.

Just make sure the perf or whatever board you're using is condensed and aint taking up too much room, and add a DPDT on/on toggle for true bypass of it and then insert it before the circuit. just put the little gain pot [5k I think?] as a trim and set it. Now you have your favorite sounds with less space, and you can double boost it with the extra SHO laying around

To get some power for it, just tap the internal adapter, but it may not hurt to just rewire the adapter and wire the stock board's power connections and the SHO's from there.
I think it'd be amazing!
