You could cheat even more by specifying a different interactive
interface, via defadvice.  :-) I gave it a try, but haven't quite got
it working:

(defadvice move-to-column (before interactive activate)
  "When called interactivly, prompt for COLUMN and interpret a prefix arg
to mean FORCE."
  (interactive "nColumn: \nP")

The first part does what I'd hoped: I'm prompted for the column, and
that's where Emacs moves point to.  But the "P" interactive spec
doesn't seem to have any effect, and neither did setting force
explicitly: (ad-set-arg 1 current-prefix-arg)
