RAM,
While I kinda like the idea, here's why not (IMHO):
It would not only be used against the strato dweeb. It would make the honest bomber pilot's, who just spent 45 minutes climbing to 23,000ft, life alot harder and a lot less fun. E.g. Why should I bother trying is as soon as I get to the target some "Rocket dweeb" is just gonna zip up to me in a minute and a half and put a bunch of 30mm shells in my belly?
The effort put in by the Bomber pilot in that scenario is in no way matched by the effort put in by the Fighter pilot.
