Ernie ball VP Jr. Mod/buffer splitter

[Tuxedo3]

Hey guys, I have an idea for a VP Jr mod to do, which is basically just implementing a buffer splitter inside the pedal to eliminate the tone suck (very similar to what JHS does, I honestly thought of this before I knew they did it). The issue is that I'm not sure how to take my buffer schematic which is super simple and make it a buffered splitter. Anyone know how to do that/ have any experience modding the VP Jr? Thanks a ton, I can post my schematic if need be.
