i have run my 2000 swift with rear disc brake conversion, was giving 2.5 deg negative camber on the rear and on the front i don't remember
you can do it, just make sure you do wheel alignement and keep in mind you may need to swap rear toe arms to make sure you can reach the right ajustement (don't know if it's required since i was using custom toe arms)
for the front it make the wheel more wide than a 89-94 i don't know if the axle can take the "stretch" if not you can shim a little between axle and bearing but may be " for offroad use only "
