Nah, the key mod for the BPP is the Vorcha - who needs accuracy when... FNNNAAASSH! FNWaaghl, Fhsneeer FshnEAAEERR! RAWHG.
Thanks to marksmad's recommendation, I put it on the Vorcha Soldier and had a seriously destructive time against Reapers. At one point during an escort I thought the little freak was going to single-handedly break my PS3. I have a slightly unorthodox build -

I found that setup much more effective than using Incendiary ammo and replacing the power amp on the BPP with the HVB - I had 50 smg kills with the former by wave 6, and only managed 25 in the whole game with the latter. I think he managed 7 medals in both games which to me is a fair reflection of variety and effectiveness. The only time I missed having a shotgun omniblade was at the very start of waves, as the first melee kill usually took a couple of goes, but after that the damage boost to both further melees and the BPP kept him going nicely. He's really bonkers, and I can't wait to try him against a BIG MACHINE!!!!!!
It also got me thinking, in a purely hypothetical sense as I'm on PS3, that built this way he must absolutely annihilate Collectors - I mean top tier, premier league annihilation, with ranged attacks from Scions and Praetorians the only things that could possibly slow him down.
(I'll also try the Cabal suggestion, which should be comparable to playing her with a Lancer I guess, which can't be bad.)
