Well, you could do something if you preserved the 2 "bootstrap" ROM's
when adding the kickstart ROM's but I doubt that he did this.  Iff the
switch allowed having the kickstart memory to sit in it's normal place,
it might be possible to run a program that would grab the system, load
the kickstart memory - then you would press reset and throw the switch
at the same time. 

The real question is why bother?  Some ancient and decrepit programs require
kickstart 1.1, but I'd like to think that future kickstart releases will be
sufficiently compatible that all you'll need to do is plug in new ROM's.
