Perhaps a short-wing Welkin?

Yes --

An article I've read said that the Welkin would only go so fast, no matter how much power was applied.  This was attributed to the thick short-chord wing but Westland' had a solution.  Which was to increase the chord by 20%.  I bought an extra CMR Welkin Mk.II to do just that.  One day I'll get around to building it --  :-X

I believe the proposed navalised Whirlwind was to have been powered with Merlins.
Perfect candidate for a brace of Bristol Centaurus I would think :)

I would say not on a Whirlwind for either engine, airframe is much too small. BTW,  I've got a couple of books on Westland and I've not found anything related to a navalized Whirlwind --

The Whirlwind's Peregrine's only put out 885 hp so you could get more power for less weight, at the cost of more drag, by fitting late model Perseus radials. This would have been idea for the ground attack role the Whirlwind was actually doing, since air-cooled radials are less vulnerable to small calibre hits on the cooling system than water-cooled engines.

Another reason why the Whirlwind wouldn't be considered for a Naval aircraft, the whole fuselage aft of the cockpit was made from magnezium alloy.  At the time of the Whirlwind concept, magnezium was a non-strategic material

Some pics I came across a while back of different armament trials for the Westland Whirlwind:

That 37 mm cannon nose is availabe in resin to convert the Airfix Whirlwind.

Or let's assume it stayed in service and got updated:
Some are convinced that the Whirlwind could have handled Merlins. Griffons might take pretty serious updating  ???

IMHO, a Merlin or Griffon Whirlwind would/should really look like this

The Whirlwind was designed around the Peregrines & could not easily be changed.

That said Petter & his design team at Westland wanted to redesign the fighter to take Merlins but the War Ministry vetoed the project because, at the time, it needed its entire Merlin production for Spitfires & Hurricanes. They, also, vetoed development of the Peregrine because it wanted Rolls Royce to concentrate its energy on developing the Merlin.

So, 2 main options I see here;

1) What if Packard began producing Merlins much earlier & there were sufficient to allow development of a Merlin powered Whirlwind, or
2) Packard production of the Merlin allowed RR time & resources to further develop the Peregrine & iron out its faults.

Whirlwind pilots, apparently loved the plane & one of their comments was that it was under-appreciated because its engine reliability & performance issues all stemmed from a lack of development opportunities which were afforded to the Spitfire & other aircraft.

So, what would a Whirlwind have looked like with a Mk. XX Peregrine, longer range internal fuel tankage (plus drop tanks) & redesigned wing to maintain performance whilst carrying a greater ordnance load?
