I am not sure "already featured" counts for much. I mean, if we are going with that, then both Aizen and Urahara are out since they have both been featured. Beside that, multiple character have 2 volume covers to their name: Orihime, Ichigo, Grimmjow, Ulquoirra, Shinji.

As for the chapters being Aizen centric, I would just like to remind you all that Gin has been on the cover 3 out of the 7 Deicide covers (399, 400, 405) so far. The Hōgyoku was on the cover of 401, Urahara on 402, with 403 having a Aizen, Ichigo and Isshin, and 404 having Aizen, Ichigo, Isshin, Urahara and Yoruichi. In short, Gin is the more secure bet at the moment.
