organic brominations using sulfuric acid, H2O2 and KBr

Because of the easy handling of the reagents, I prefer using HBr and H2O2 to do bromination of organic compounds, if bromine is the needed reagent. As long as temperature is low, there seems to be no catalytic side reactions.

The stuff that interests me at this moment is aromatic substitution and catalytic bromination of (cyclo)alkanes.

How about using H2SO4 and KBr instead of HBr, using large dilution? Are there any negatives here? Given the low temperature I don't see anything nasty that could happen. Or is there a nasty interaction I am overlooking?
