You could leave the stuff there. It's not 100% clean because of the 
misnamings but technically ok.

Use the upgrade hook of the EM.

I don't know the exact specs, but if your ext. has a 
class.ext_update.php it will be available as UPDATE in the EM drop down 
of the ext. See for an example class.ext_update.php.

If you're really moving stuff arouond, why don't you make a new 
extension wm_banner and mark both extensions as obsolete. Then the 
renamimg of the tables would at least make some sense the the users of 
wm_wsbannerplus.
