Doyle would score similar amounts to Carew and would do Heskey's hold up role better than he does. And there would be no issue around inconsistency either. Get rid of both of them, bring in Doyle, flog Luke Young to Blunderland and try to get Kenwyne Jones on the cheap in return for the bench. Voila, Doyle/Gabby partnership with Jones/Delfouneso as backup. Though I'd personally be more inclined to use the Fonz in more than just a backup. I'd nearly (nearly) alternate him with Gabby in maybe a 70-30 split.
