Don't know if this has been suggested before and I know you already have a heap of tele's available, but I would love to have a crack at a cabronita.
Rear routed controls, pickup cavities for humbuckers and a set of retrotron style pickups like on the GR-1SF kit.
I prefer the solid bodies but could be done as a thinline too.
Found a pic of a body that shows what I mean, could also do a single pickup version.
