Could you increase the stroke on a 307 using a 305 or even 350 crank, and would that even be streetable?

I've read of some fellows doing this with 400 rods, 350/305 crank, 307 pistons for a stack of 8.980". I'm not sure how the piston skirts/crank counterweights would like it. You would have to balance the whole mess and that alone would make it less cost efficient than starting with a 350 short block in the first place in my opinion. Well, that, and the fact that you end up with a 328 instead of a 350.
