Should at least be an option, and if -- as I suggested -- you did not *have* scenarios, and instead allowed the challenger to pick the planes, then it would be up to the challengee to accept, or not. If it is unbalanced enough, and if the challenger does not accept in the inverse, then basic economics will see that combination die off. But it should at least be an option.

Frankly, some of th analysis if what constitutes balanced (or not) and popular (or not), is probably due to the few of us who generate the the over-whelming majority of the games for that scenario, which without that distortion would be revealed for the crap fest it is.
