Pat, I wasn't really serious with the ECW; I'd like it, yes, but I can think of (at least) 10 other sets I'd prefer (all of them WW1 British).
I also think it's great that HaT have overcome their difficulty and are starting to make figures again. Even if the ones they are choosing, such as anything ACW, just send me to sleep. That's fine. All the projects will get done, as long as the crowd funds them.
But you've spotlighted the brilliance of crowdfunding - there are a lot of people who talk a lot about how many brazilians of sets they'd buy of this and that, but crowdfunding cuts out the chaff. If the set isn't popular enough it doesn't get made. End of story.

Personally, I think crowdfunding is the best thing that could have happened to figures and model making.
My suggestion for a quick and easy money maker is to pinpoint a war or era that is lacking figures but has popular appeal and requires fairly large amount of troops. So that narrows it down to the English Civil War.
English Civil War and/or Thirty Years War. I'd buy plenty of both, for historical and Lord Kalvan armies.
"I suggest a quick easy money maker is to MAC the existing British Peninsular set and provide extra sprues of alternate heads - 1812 and tapered light infantry shakos. The molds already exist..."
I think there maybe a fundamental misunderstanding of how plastic figure molds are made here. The mold that already exists will make the set that already exists you cannot use it to make different sets. You may be able to use the master figures to make a new mold if they survived the mold-making process but that is a pretty expensive process.
