(I'm going through old bug reports that unfortunately have not received
any responses yet.)

I don't think there's any way to do what you want.  (Somebody correct me
if I'm wrong.)  And I don't really see how an interface that does this
would work, really.  Something like

(with-everything-interactive-if-this-is-interactive
  (adaptive-wrap-prefix-mode)
  (window-margin-mode))

Well, in this case that would be a pretty trivial macro to write, but I
don't see this as being generally useful.  So I'm closing this as a
"wontfix".
