How are you intending to do this?  It might be easiest to just re-run the entire
DRC with different settings, then throw out everything that doesn't involve
objects with different netclasses.  This is maybe a little hackish but DRC is
already sort of due for a rewrite anyway.  I guess this wouldn't help with
incremental if that's your preferred way.

However as John has pointed out in the past existing DRC is no good between
layers etc. so depending on what you want to do this might not be enough.
I think fixing DRC to be fully conscious of interlayer interactions
might be better
done with a rewrite than by trying to change the existing stuff.
