Keep in mind the F52's have the "contour" controls for highs & bass, this would be integrated into the crossover networks. So I wouldn't do anything to the internal crossover. What you are planning to do should work fine. My only concern would be how low the impedance might drop on the top end of the speaker and how tubes would do with that.
The F52s seem to love the more current you can feed them. I originally drove F52's with Conrad Johnson monoblocks but they really came to life with a Pass X250. I never played with biamping them. I'd be interested to see how the biamping works for you.

With the 470C doing the grunt work, it would seem that a good tube amp should be able keep up with a much lighter chore.
I looked around and I`m thinking the top is basically an M22 and there was a review here on the M22`s where he ran them with 25w Mini Mites with satisfying results though admitting that more power would probably work better.
So I`m still thinking 45-70 tube watts could do it.
A Rogue Atlas would do it no doubt, but a lower power (less expensive) Jolida, PrimaLuna, QuickSilver and the like may do it as well.
I can always have my buddy drag the Rogue ST 90 back over too :)
I am a big fan of the F52, I especially enjoyed the very low response and detail.
I think biamping them could be interesting, for nothing else a bit more control over the balance of high to low end. Sometimes I wished I could get more power to the bass without boosting the highs any more, which is odd considering how many bass drivers those things have.
I agree and using the 470C for the woofers I can dial up on the bass too.
I`m also cheating in a sense..I`m using a Revel Ultimate Sub 15 with a 900 watt amp that fills in the bottom.
It`s been 3 months and just recently added a Rogue Atlas Magnum to power the top end of the Revels.
For the bottom section of the Revels I have the SDS 470 amps volume controls set at about 3/4 open using a 80hz high pass from the subwoofer amp.
Still tweeking the subwoofer crossover but so far it sounds pretty nice.
