Sure that makes sense, I have a conical so I feel as though I get rid of most yeast before dryhopping, but still some is there, take the best of what's left and use that.. it's an interesting theory, I'd have to do a small batch to try it, I could take a clean dump (doesn't sound clean at all haha) from my 15gal conical and use what looks best for the whirlpool of a 5 gallon batch... almost like when you harvest yeast, you get rid of the first bit, keep the middle and leave the rest behind. The wheels are turning brother...
