It can be done with multiple data arithmetic, you should select with mask m1 the data you want from first image a1, than invert this mask (m2) and apply to second data (a2), than combine both with a1 * m1 + a2 * m2 (or (a1 * m1 + a2 * m2) / (m1 + m2) if you have intersecting masks and do not have voids that are not covered by any mask).
