Looking at a cutaway drawing of the Stirling, I note it was built with dual controls, a galley, elsan and bunk as standard. Maybe add a second bunk and some additional galley stores?
For a quick and dirty MkI MPA, how about replacing the forward turret with a glazed nose and mounting three...
Any impact will also be governed by circumstances. As an example, if both fleets sortie but never meet, might this be viewed post-war as due to a failure to locate the enemy and lead to programmes for light "scout" aircraft carriers?

1 - I think the Shark is often overlooked, particularly given it's performance when re-engined with the Bristol Pegasus (which arguably it should have had earlier?).
2 - There's always the chance of a crippling hit, but note the OP says the final sinking was by 21" torps from the cruiser(s).

More likely to gain export orders? Something akin to the MiG21?
I'm liking this! I've suggested in other threads that the RNN could have purchased one of the surplus RN battlecruisers post WWI, but that was always going to be pushing the bounds in terms of funding, manning and utility. This looks as if it could lead to a more affordable and sustainable...
I'm sure this isn't news to many, but following on from the EMF and early 30's exercises - https://en.wikipedia.org/wiki/Experimental_Mechanized_Force#The_future_British_Army,_1935 - The General Staff also wrote a "Forecast of the Opening Stages of a War with Germany" (1935) in which the First...
One of the problems with questions like this is they eventually seem to end up concentrating on hardware - tanks in particular. (And I'm as guilty as anyone - https://www.alternatehistory.com/forum/threads/improved-early-war-british-tanks.488684/ )
But what can be done from 1935 to improve...
True, but bear in mind that Nazi Germany was resource constrained. The majority of their tanks in France were Pzkpfw I and II, and 35t and 38t. While Britain, given a start date of the mid thirties, could have an easier time of it (assuming the will is there to do something) I'm not convinced...
I don't know if twinned engines would fit in the Valentine, which was designed to be as small as possible.
Can't find and dimensions for the AEC engines. The GMC 6-71 was 1.37L x 0.74W x 0.99H according to Wiki, so I assume they must have been in the same ballpark.
Just as a comparison...
