'77 cj-5 with the 4" HD Superlift fit 35 thronbirds for 2 years, and probably would've fit the q78's for a year, maybe two... this was with stock shackles etc. The superlift didn't have enough flex to worry about bumpstops etc... Stock axles will mean your turning radius will be hurt, and you may rub on the frame and inner fenderwells in the rear, and definately rub the springs in turns. 4" and a spring over will be too tall for the narrow axles, I'm contemplating it with mine, but I have full size axles. 33's will look like doughnuts, but they won't rub as bad as the q78's on the springs. I'd get as narrow a tire as you could tho, for turning reasons.
