Don’t forget that the Gurkhas used a hat kinda similar to the Aussie hat. I think a hat-wearing Commonwealth/ FEC soldier would be one of my highest priorities for a UK-oriented set. Perhaps even a second in proper Gurkha-gear wielding a kukri overhead! With FMG doing KBV, Nelson would be a good choice, as I hear WotC is doing Hood (strange choice though it is) for their joint-allied BB in AA41.
The Aussie Sentinels and Canadian Ram/Grizzle series were not used much, and are basically derived from US tanks (M3/M4 series) anyways. I’d rather see someone do some of the late-war tanks for the UK set proper: Comet or Cromwell, maybe, though I don’t know what FMG is doing. The Cromwell was the second-most used UK tank after…. drum-roll, please… the Sherman! Yes folks, the Brits used more Shermans than any one particular tank of their own design. The Churchill is distinctive and cool-looking, so I wouldn’t mind having some, but the fact remains that it really wasn’t that great of a tank, and the British couldn’t wait to get their hands on Shermans because, quite frankly, they were better than anything the Brits produced until the Comet and the Centurion (the latter of which came too late to see action.)
(OK, the Cromwell was better than the original Sherman in some ways, especially mobility, but it was too tight of a design for its gun to be upgraded, unlike the Sherman.) Anyway, the Comet comes closest to being something that the UK player could used as a “heavy” tank upgrade, since, unlike the Churchill, its gun was at least competitive and its superior mobility gave it some advantages over the Tigers. Yes, the Churchill was a comparatively “heavy” tank, but what’s the point of a “heavy” tank with a weak gun and thin armor that was way less mobile than a Tiger on top of it all?
