I note that they also have a Faithless, MiG-23PD, among their other releases besides the Yak-36 and Yak-141. There's lots of whiffing potential in that one, especially if the lift engines are removed. I'm thinking of inlet-mounted canards similar to those on the Kfir as a starting place, possibly with reduced leading-edge sweep outer panels to allow tip-mounted IRAAMs.
