I was thinking of buying a Road Worn JM body that typically has a 7.25'' radius neck but instead of using one of those, just use a 9.5'' radius neck instead, would it be possible?
Shouldn't be a problem at all. I'll be judging you, though.
No problems there, so long as you can adjust the bridge to the correct radius, which you normally can on a jazzmaster.
K33nbl4d3 It's just cause the 7.25" is so much more expensive and hard to find x)
Thank you all for answering the question.
