Yes, absolutely. Compensate for any displaced internal volume by "growing" the cabinet to make up for the difference.
In this case, internal standing waves aren't possible because cabinet dimensions are so much smaller than a wavelength throughout the passband. So you don't need to worry about standing wave issues when you modify the dimensions of an acoustically small subwoofer cabinet.
