Has anyone ever made???

Hi all just wondering has anyone ever made sticks that have a tip and shaft of a 7A stick and a butt end of say a 5A?? I find that after playing with hot rods (or equivalent) that switching back can feel quite weird.
Just curious

Maybe the Vic Firth American Jazz series would be the closest. That I know of anyways.

The AJ2 is a 5A stick with a bit more taper than a regular 5A; the tip is also a bit smaller.

That might be what you are looking for.
