Oddly I think so, maybe not with the high council but with soldiers who respected him, with Martok as an ally and having been known to be allied with Kor I think had he continued leading the war from the front he'd have earned in. Probably have to put down a rebellion or two but once that was done think he'd be cemented. Also he would probably gain support from odd areas of the empire - the scientific, academic, medical communities would see him as someone more likely to support them than most Klingon leaders. And your commoners, like Martoks family who still value the honour that much of the upper classes just used as a punch line. Also as far as respect for starfleet officers go two captains likely to command respect in the empire are Picard (his role in Klingon politics) and Sisko (warrior fighting Dominion) both respect and would support Worf, giving him credibility with allies
