Hi Guppy,

Well, I'd agree Beaufighter before Whirlwind is the way to go for Aces High.
Reengineering the Whirlwind for the Beaufighter was considered, but it proved impossible without a complete redesign (think F-18E/F ;-) so that's a much bigger "What if" than the "reliable Peregrines" idea. You might as well consider a redesign for Vulture engines, which would be sort of logical, too :-)
