But the other poster is right, if it hadn't been the Merlin, it would have been something else. The UK had more than Rolls Royce doing engines.
If we would have lost all our Allies in Europe would have we gone there? In what timeframe?
When Russia was turned on would have we (I mean US) given them arms to do this battle given that we had few options to attack Fortress UK AND Fortress Europe?
What other engine was developed and in fighter aircraft and equipped squadrons for the Brits in the late 39-41 timeframe? What fighters were they in?
The Spitfire really wasn't that wanted by the RAF originally. The Hurricane got the bigger order initially IIRC. Other attack aircraft available was the Bolton Paul Defiant, with a Merlin. It saw limited success but had horrendous losses at times.
If there wasn't the Merlin then there wouldn't have been the P-51D.
As I thought I (and others) made clear, without the UK in the war, it winning would have been a very longtime process. And much more costly to the USA.
I don't see America ever bombing the UK, since I
think they would have been politically neutralized rather than invaded.
And the UK
did have other engines, radials and other inline designs..Bristols like those used in prewar Gladiator fighters, Napiers, Armstrong Siddleys...
Asking about other in-line engines in othe RAF fighters is silly because the Merlin worked so well, none were developed.

That's like asking about other small Ford "muscle cars" other than the Mustang. They weren't built because the Mustang was a hit.
Many weren't developed because the Merlin worked so well.
And remember, the Merlin wasn't a "clean sheet" design, it was a scaled up Kestrel. Since that was a successful engine, I can't imagine it
not working in
some form.
Rolls had a line of in-line engines other than the Merlin, though some, like the Vultures, turned out to be duds.
The Defiant wasn't an attack aircraft, it was a fighter. The Whirlwind was more of an attack aircraft inasmuch as it was designed as a fighter-bomber. It was powered by a Merlin...it's failure had nothing to do with the engine, rather the concept of the turret-equipped fighter.
I can't agree with your assessment that the Air Ministry wanted the Hurricane more than the Spitfire.
The prototype first flew in March of 1936 and the RAF ordered 310 in June. Sounds like they wanted it to me. Like many wartime aircraft, it went through many changes before being built, in the Spitfires case there were two Air Ministry speciifications before the one that produced the prototype.
The Spitfire was seen as a more modern fighter, but the RAF bought the Hurricane in part because of the success of past Hawker fighters like the Fury, while Supermarine had never built a fighter before and was seen as more technically daring. Certainly, Supermarine's design was going to be more difficult to build. Remember too, that Supermarine was a small firm and had never built 310 of
anything, though part of the larger Vickers-Armstrong group.
It certainly wasn't a sitution like the US bomber competition where the USAAC ordered the B-18 because the B-17 was too expensive. And it certainly wasn't a case like the P-51 where it was adopted through the back door. One aircraft the RAF didn't want at first was the Mosquito...they didn't believe in it and didn't have a specification for it but were quickly converted.
And on your final point, if there was no Merlin, I'm sure Allision/Packard/P&W/Wright/Chrysler...would have come up with
something.
