Isn't the speed increase a sign that the wind shear is over? Ok, there may be a second speed loss etc. but at some point one finally has to resume normal ops...
I would also be careful about pitching up above the FD. IIRC SRS w/s recovery mode limits the pitch to 22 degrees (or thereabouts) pitching significantly higher than that could put the a/c in an undesired energy state...
Also, a minor flap over speed is no drama - wings won't fall off...
