Yes, the 50 VAC will become about 70 VDC after rectification. But you cannot get more power after the rectifier than before, so the 24 A @50 VAC will go down to something like 17 A @ 70 VDC.
50 VAC * 1.4 = 70 VDC.
24 AAC / 1.4 = 17 ADC.
It doesn't really matter much what voltage you give the motors, as long as you have the current limit set correctly on the Geckos and the voltage is not too far off.
