Adding the SS/BS crackle circuit to a BJT fuzz HELP!

I've got a @#$% OD which i really like for its compression/crackle at high gain settings but I feel like I'm trying to get something out of the pedal it juuuuust doesn't want to do so I'm going to design my own fuzz. Well... actually I just want to bolt this onto the carcosa fuzz since that's one of my favorites and is relatively easy to build.

The @#$% basically uses this circuit https://tech.thetonegod.com/punisher/punisher.html to mis-bias the 2nd jfet - a variation on the envelope portion of the Dr.Q filter. I'd like to use it to mis-bias a BJT in this circuit https://i.imgur.com/fIJdViV.png, specifically Q3. I can read a schematic and understand the bare basics of pedal/amplifier design but not much beyond that and am finding myself having a hard time getting from the envelope follower to how to implement the punisher schematic to achieve a similar effect to the @#$%. Does it replace the entire bias network of R11/R14, would you simply replace the supply voltage at the top of R11 with the Power Out from the Punisher or ...? Any help in understanding how exactly this works electrically would be incredibly helpful. I understand the envelope follower and how that works, its more the bit from the 2N5457 on (on the punisher circuit) and how varying the bias current effects the biasing of the bjt's vs the jfets in the @#$%.

Thanks in advance!

this, exactly this.
