A Lancaster with radial engines??? I didn't know they had one. Well I
guess they'll try lots of different experiments and variants in order to
get the finished production design right. Presumable the RR Merlins didn't
grow on tree's.

Yes. They used Bristol Hercules VI or XVI radials and called them
Lancaster Mk II. This mark was a poor performer and
only 301 built.

Oddly the Halifax started life with the Merlin engines and
for the MkIII they switched to radials and increased the wing
area and it showed improved performance.
