There are Sense roms, but none with Froyo. We'll have to wait until the official update comes out first.
If you want the full-on stock interface, I'd grab CR_Mod_1.35.531_OTA Full ROM
SLIDE MR1: Version 4 Final
is a Sense rom and what I was using before going to CR Mod.
I'm on CM6-RC1
now, and it's one of the most stable roms I've used. No Sense though. The dialer was one of the big things I missed from Sense, but I found Dialer One that functions close enough for me. Screenshot below. Oh, and it has a dark theme as well.
