There's no issues, but someone needs to write the code for it. I can't
work on Kicad right now, so if you want it done fast, you can contribute
a patch.
The starting point is:

int DIFF_PAIR_PLACER::matchDpSuffix( wxString aNetName, wxString&
aComplementNet, wxString& aBaseDpName )

Also, it might be worth adding support for diff pair busses (e.g.
PAIR0_N, PAIR0_P, PAIR1_N, and so on).

Cheers,
Tom
