I'd like to lift up my Impreza SW 1997 to increase its floor clearance. I've read that changing the struts with Forester ones works, but I'm afraid about alignment measures, > i.e. camber, toe-in, convergence, etc. Have you guys heard something about it?

you will stil be able to get back to your stock settings if thats what your wondering about..... if you use the springs you might want to look into getting camber bolts......

i have a 97 Imp coupe lifted with struts/springs off a 99 Forester, gained ~3" over stock, Toe is fine but the camber is tough even with bolts, its not bad enough to really worry, but the rear caster? i don't mind and i drive all day around downtown as a courier, the fun and looks i get are well worth the little annoyances,
