I have not tried it, so I obviously can't tell you for fact. But I don't see why it wouldn't work? You'd probably just shorten the lifespan of your stock twins since they'd be used at a higher level.

I hesitate to give advice to the guy who won Street 8 at SILV05, but I'm not a fan of that combo though I've never tried it...simply based on the fact that the stock twins peter out of breath in the low 6000rpm range which seems too low to gain the benefit of 272's. So you give up too much area under the curve on the low end and only pick up a peak at the top end which I think is a loosing proposition.

But if you build the head and have 272's you'll be in good shape when/if you go with a large turbo.
