Could Mosquito-style six-pounders arm a submarine-hunting Lancaster?

Could the six-pounder system used by the Mosquito be adapted for the proposed Lancaster submarine hunter?

The suggestion becomes twin downward-firing six-pounders used during level passes, with feasibility left open.

The Mosquito's six-pounder installation provides the starting point for a proposed Lancaster adaptation. Twin six-pounders in casemate-like positions would fire down as the aircraft passed over the target. It would turn back for another pass while remaining in level flight. The idea attracts interest, but installation, aiming and operational performance remain unresolved.
