I wouldn't touch FR with a 10' pole.
I'd either use Eberron or the Earthdawn setting for 4E Age of Legend. Since neither is out right now, I'd start with a homebrew or the default setting.
I completely agree. Aside from a few crunchy bits in the FR Players Guide, 4E FR has significantly underwhelmed me. Aside from Eberron and Earthdawn, I think Cyradon, from ICE would be a great setting to start a new game.
