That's the biggest concern to watch, is the capacity of the RD. 27 or 28t is pushing the top limit on many road components, and with 32t you might not have the clearance for the jockey pulley.
I used a Tiagra mid-cage RD with an 11-32 cassette; but it took a bit of fiddling with the B-screw to keep the pulley off the cogs; and even then, it just barely cleared.
