There is nothing against using landing flaps after a commitment to land(Short finals).Thrust required will never be more that 65% N1, if you are heavy.Would also depend on Field length available permitting a 15 landing.The only issue here would be a Flap 15 or A fLAP 1 go-around with one Thrust lever in mid position.Try opening all bleed valves and advancing the thrust.May be that will almost definately slve the problem.
