Yes, you can, but then you'd have to re-install SP2.
I've tested it; don't try it at home, kids. It's not pretty. The sp1
repair install leaves some non-functional sp2 stuff behind (like the
Security Center, wierded out firewall settings, to name two I noticed
and recall off-hand) and the subsequent re-install of sp2 make things
even wierder; parts of it think sp2 is already there because it sees
certain leftovers and then they may not work right. In my test cases (3)
I wound up with duplicated & orphaned accounts, too.
That would be my recommendation, but you don't have to do so.
Create an installation CD with SP2 integrated, and the
installation/repair will go much more quickly.

Definitely the way to go. The only excuse not to slipstream is if you
have no CD burner, even then it's a flimsy one at best. Everybody knows
somebody with a CD burner, easy to use slipstreaming software is free
(like Autostreamer) and it only takes about 10 minutes.
