need some help for my modification - treble booster with clean blend

Hi, guys.
I need an error check for pedal modification, can you give me an opinion if it's okay?
I pray that the anomalous communication caused by using a translator doesn't confuse you too much

The circuit diagram and artwork below are the pedals I'm trying to make this time
Intended to add a Clean Blend knob based on the PPCB Dragon Breath pedal (https://www.pedalpcb.com/product/pcb402/)

I made it with reference to the 3. "Additive" Op Amp Blend circuit of this post on the forum, and added an inverting jfet buffer to reverse the inverted phase
(https://forum.pedalpcb.com/threads/why-your-clean-blends-suck-or-how-to-clean-blend.20986/)

Looking at it, I think the jfet inverting buffer block is designed to be a complete sham

As long as I decided to make a treble booster, it seems inevitable that the signal will flip once, is there a way to complete the circuit without using a second OPAMP?
