I've also rewired "gibson 50s style", and while there are indeed some interactions between volume and tone pot, I don't have any of the extreme side-effects you mention - I'd even say it made the volume pot taper smoother and more manageable. The pots are the stock ones (japanese mini-pots, 250Ko audio taper), but this wiring works fine too on both my Vox Custom 24 (LP-like, CTS 500Ko audio pots) and Standard 25 (strat-like, stock japanese 250Ko pots).
Could check what kind of pots you have and post a drawing of your wiring ?
