Design a clamping piece, that grips the heatsink on its lower fins.
This way you have no issues with too much heat rising into the plate.

Just tap 6mm (or 4mm for Prometheus) threads in the plate. Thread the nozzle into the plate leaving 2mm to 3mm exposed for the heatbreak. Thread the heatsink onto the top of the nozzle until it hits the plate

Why not just elevate the grove mount using some posts like they do on the Rostock Max from SeeMeCNC?

I have that in sight too but drilling holes is much easier than cutting notches into metal plates. I have the following design:

This will make it not much different than the existing ALU upper-heatsink-mounts and more tools will be needed to cut the metal plate (Dremel or similar).

You could design a printed clamping part. It wouldn't add cooling capabilities, but you don't have to CNC/dremel a big hole.

That's what I have in mind. The temperature of the heatsink fins should not exceed 40C when printing PLA and maybe 60C when printing ABS, so a PETG or ABS printed part would be OK. The print would also accommodate the cooling fan. The only thing I haven't worked out yet is how to mount the IR sensor.

This design would have a too small contact area between M6 heatbarrier and the rectangular heatsink. This would make the melting zone very long.
IMHO the cold zone would start above the fins.
Furthermore, you don't use commonly available parts. E3d clones unfortunately are commonly available, so we have to make the best of it
