199 inputs, 35kb tx with a tiny 0.0003 fee. 
There's minrelaytxfee, but I'm looking for something that is based on both fee and tx size. 

user5292: minrelayfee is already in BTC/kB, so that's exactly what you need.

35kb tx with a tiny 0.0003 fee.

Didn't do the math, but I think even the default minrelayfee should block those.
