Reject TXs based on fee in comparison to TX size? Is it possible to configure a node to reject junk transactions like this

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

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