I have looked at getting a new gun myself, a 20 ga. If one of those Browning made Model 12 20ga would shoot 3" shells I'd already have one.
Been thinking on redoing my old(45 years) double 20ga. It has 3" chambers, just would have to get the barrels fitted for screw in chokes. Already has a sling and a warthog ivory front bead.

You could start loading tss and probably get a good pattern with the fixed chokes.
After reading a few hours, looks like this project may be too much trouble and expense. I might try something similar to what you are thinking - fix up my grandfather's old Stevens 311. Might do a little testing with it to see how to shoots first. I've shot doves and quail with it, but never tested turkey shells in it.
