Actually I think grammatically speaking "dou sureba nyuute dekiru deshou ka", or "dekiru you ni dou shitara ii no ka" would be more preferred than the above. Since the potential form dekiru is used, "-ba" form should be a better choice than "-tara" for if. But I think in Kansai everybody uses -tara over -ba regardless.
