It think it's fine, like I think it's going to be profitable and even when called by even vs those rag aces/middle pairs/TJ/QJ etcetc it's not a terrible spot to be in. Besdies which it's a KO tournament so hands he might normally fold will probably call. I think he's nearly committed with most of his hands and not folding often though given you're on 8bb so don't expect to many folds.
