so this is a bit daft and it almost makes more sense to start from scratch.
but i have been asked to see if i can convert a headless steinberger style hohner cricket bat into something more like a flying V. Not a steinberger mini v shape but actual flying V styling
so here are the preliminary mockups showing potential sizes and styles next to the source guitars (controls and pickups are not to scale)

essentially I will be trimming the original guitar down to just past its pickups/bridge routes and treating it as a neck through - but am also considering doing it as a full new body so the original centre section can slot into it
I am pushing for the large scratchplate style as it will hide a lot of sins
...
probably the most shocking thing about this idea is that its not for gWem ;)
