Avro Manchester (1 Viewer)

What if the Avro Manchester was designed from the outset with the Rolls-Royce Merlin and then of course the four engined development of the Lancaster.

Would the need for other two engined mediums been avoided?

Not sure when you are talking about.
The class of '36 medium bombers are later in timing to the Vickers Wellington and cousins.
The Class of '36 includes.
Avro 679
Boulton Paul P.91
Bristol P.13/36 (Hercules engines)
Fairey P.13/36 (P.24 engines)
Handley Page HP.56
Hawker P.13/36
Shorts P.13/36
Vickers P.13/36

All of the aircraft design except the ones noted were to use the Vulture engines. 2 had Sabre alternates.
Goals for all was the requirement to carry 8000lb of bombs 2,000 miles and go 3,000 miles with a lighter load.
desired max Cruise speed was 275mph.
There is no way any Merlin being contemplated in 1936-37 could offer that sort of performance so there was no such proposal. Even late war Merlins could not offer the performance desired, max combat is not 30 minute climb performance.
