Your guitar having individual Volume and Tone pots makes this unlikely to be feasible. Granted, this is my gut feel without me sitting down to formally try and figure out the wiring circuit for this, but the reason I say this is I think there's too many wire connections involved when you have individual Volume and Tone pots vs just Master Volume and Master Tone, to do BOTH Kill Switch functionality AND Post Bypass functionality (a.k.a. "Blower Switch") in a SINGLE switch of this type, i.e. 3 way DPDT, which only has six lugs.
Let me break that down to show you what I mean:
A) Kill Switch functionality: 3 wires involved: Wire 1: hot wire from 3 way Toggle Switch that gets re-routed from going to the "Tip" of the Output Jack, to the Kill Switch. Wire 2: when Kill Switch is not active, wire connecting Hot Signal to Output Jack "tip" lug. Wire 3: when Kill Switch is active, wire connecting Hot Signal to Ground.
B) Bypass Pots functionality (a.k.a. "Blower Switch"): 4 OTHER wires minimally involved: Wire 4: Neck pickup hot signal that normally goes to the Neck Volume pot, now gets routed to this Switch, Wire 5: Wire from this Switch to the Neck Volume pot when this switch's Blower mode is Not Active, Wire 6: Bridge pickup hot signal that normally goes to the Bridge Volume pot, now gets routed to this Switch, Wire 7: Wire from this Switch to the Bridge Volume pot when this switch's Blower mode is Not Active.
Total of 7 distinct connections needed, but a 3 way DPDT switch only has six lugs. If you must use a 3 way DPDT switch, you can get one of the two functionalities, but not both. Or, be willing to change your current circuit configuration so you only have Master Volume and Master Tone.
