Yes, there is no way to compile locked S+ modules - why don't ask this feature from TB?
My advise is to wait for a year of using series 3 in commercial projects)
But if situation is exigent (have you another when installing?), let's send me the locked USPs (except serial/activation protect routines, of cause) - I'll recompile em on current S+ for series 3 and send back locked without compile log for keeping developer's shame)
