It's not a grey area.
If not in SRS because of a stupidly low acc alt, set TOGA with AP engaged. If SRS doesn't re-engage - which it possibly will - then do as vilas said - take over. That means AP off, FDs off and pitch for 17.5 degrees using full back stick if necessary.
I say SRS probably will because:
In windshear conditions, flight guidance acts on specially adapted FD pitch orders received from the speed reference system (SRS). The pilot must set go around thrust immediately (which also triggers the FD SRS mode), and follow the pitch order to execute the optimum escape maneuver.

It's an assumption but there is probably a logic that if below 1300 RA, CONF 1 and TOGA is applied then SRS will re-engage. If you'd retracted before 1300 feet RA (extremely unlikely) then I don't think it'd re-engage.
