Welcome to Chopped Spoole! Let me know as you go through your process of pricing out different tree rake kits, more than happy to help you out - Shoot me a PM if you are looking for pricing on any HHI parts as we get them at a discount.
I can't think of anyone off the top of my head with that setup, you may be the first on our forum.
There seems to be a little bit of wiggle room in the tree/neck debate, so if that's the route you want to go I say go for it...
If you are looking for that stuffed look you could always tack the neck on and see how it looks with the frontend mounted prior to any serious welding. That way if you have clearance issues you could take it all off and resell.
