I think your description of the question as pointless is rude and marks you out as somewhat ignorant.
A great many circling approaches have MDA=MApp stop alt.
Hitting TOGA whilst in ALT or VS0 will engage SRS if you are not clean and cause a rapid climb. Procedure described above will work. However, if you are on an A/C with FMS1 standard it may be an idea to temporarily select a TO WPT some distance away as the FMGC will enter DONE mode as you pass over the airfield and dump your beautifully crafted F-PLN.
