"Change of Heart" happened over half-way through S6, well into the DW. Add to that his actions in "Rules of Engagement" and a few other questionable decisions, over the years and I'd say that he'd be pretty low in the pile of officers up for command.
Besides, Worf has had his day. There isn't much else to really explore with the character, and any Worf series would once again be filled with many episodes on Klingon honour :yawn:
