My concern like the o.p. is track conditions. If midget week is any indication, track surface will take a beating. I'm willing, and do forgive the occasional hard, slicky but two big tire classes all season to me almost guarantees that to happen. Especially if one of them is winged.

If it's still worth the risk, then what about mandating 3 digit numbers and mufflers to differentiate? Or the old handkerchief tied to the cage?
