We'll, I tried it yesterday. I would not recommend it. After the boil, I put a paint strainer in the pot, and turned on the pump to recirculate into the strainer. For some reason, the hops completely clogged the strainer. I ended up with a giant balloon of hot wort. It got a lot of the hops out, but was not worth the mess and extra work. I think I'll go back to using the strainer for the whole boil, and adding my hops to it.
