Practical sense or not, it's fun! Then again I'm the type that turned a telecaster into a death metal shred machine just because.

Sometimes practicality can be overrated.

It's literally a jug and piston swap and it's absolutely practical. The jetting will be nearly the same. The o.p. of this thread way overcomplicated shit and made a lot of guesses and mistakes including the "while I'm in here I might as well" disease. Swap the piston and jug and get on with life.
