Yeah, sounds like a small tapered shim at the heel would just sort it, but as you say, it’s all gravy.
Never put your tools away, there is always something else to tinker with!
Honestly those countersunk angled bolts are not massively new tech or voodoo hoodoo, actually the same principle applies to the straight 4 bolts with a lag screw principle.
The body hole is slightly overdrilled so the screw does not bite, therefore when you tighten it, it pulls the other object (neck in this instance), into the body. It’s used all the time in other applications
So the top 4 screws will not be an issue at all, the counter sunk angled screws are just performing like a lag screw principle so in all likelihood they are insetting right at the heel into the neck substance.
The amount of shim you will need to get a perfect action will be minimal from what you say, you could take the neck off, mess about with a couple of playing cards to get the amount of shim height, tapering angle etc you need before slipping a nice veneer in there and do it right. Drilling through a bit of wood so thin for that job is lemon squeeze.
May just make it just perfect for you, no more will it won’t it hassles
You don’t have to convince me on the tonestyler.
