I have a recirculating ebiab setup and just burned my pump out by recirculating my wort through the grain bag containing all my whirlpool hops. It worked well for a bit, but all the pellet hops eventually clogged up every possible inch of the grain bag until the bag could no longer drain fast enough to keep up with the pump... so I ran the pump dry for who knows how long since I was drinking and chatting with friends.
I liked the idea of it because it meant all my wort was passing through my hops, but in practice its a PITA.
I'm not sure if you actually intended to recirculate through the bag containing the hops or not. It would work just fine I imagine if you had the bag tied or clipped to the side of the kettle and recirculated outside of the bag or used whole hops.
Hope that helps!
