A Boss LS-2 will do half of it, i.e. blending the B7K with an EQ'ed clean signal. Put the B7K and EQ in separate loops. Ignore the parallel out of the B7K and let the LS-2 split your signal for you. Set the mix levels with the LS-2, then if you want to bypass the EQ and just have the B7K blended with clean, just turn off the EQ. Or if you just want the B7K soloed, hit the LS-2 to switch to just that loop instead of the mix of A+B.
Alternatively, SFX also do a simple mini mix pedal that sums two pedals together - you could use this instead of the above to blend the output of the EQ pedal and the B7K effect out. Since they both have volume knobs you can do without them!
That's the blend portion out of the way - then just use a separate true bypass loop for the rest of the wah/fuzz chain.
But if you want it all in one box, I would hit up SFX, COG, Bright Onion, etc!
