No, because the PTU uses Sys A(!) pressure (which you have lost) and feeds the autoslats and leading edge flaps. Plus, it only operates when Sys B pump pressure drops below limits (+ airborne + flaps >up<15).
But you can still raise the gear via the LTV (landig gear transfer valve), which operates automatically when airborne + eng.1 RPM below limits + landing gear lever up + either main gear not up & locked. This valve allows Sys B to supply the amount of fluid to raise the gear.
happy landings
