I think the turn donk will be a made hand more often than a semibluff. (I think just in general this will be the case, but also the fact that you hold the J [img]/images/graemlins/spade.gif[/img] and J [img]/images/graemlins/club.gif[/img] cuts down on the number of available semibluffing hands.)

So is it KQ? AQ? AT? 99?

Beats me.

I suppose A [img]/images/graemlins/club.gif[/img] T [img]/images/graemlins/club.gif[/img] specifically is a possibility too, as is a sort of delayed clubs semibluff. I don't think you'll end up seeing a flush that often, but it's something to at least consider.
