Air chisel from the back side.  Grade 8 fine thread bolts for the replacement hangers.

Need more info on what you are working on but to get the rivets out, grind an X in the head and then hit it with an air chisel.

If I'm ditching the old hangers, I torch off the rivet heads and punch out the rest, If I'm pulling off old hangers to use, I heat the heads til they glow cherry red but not til they start to oxidize, and one solid whack with a 3 lb hammer and a cold chisel takes em right off.
