There will always be be some outliers- such as the historic Hispano-Suiza 12Y-51 which was the pinnacle of that design arc, where the historic engine should be used as is.
Dont really understand what you are trying to say with this?

Yes, but if you look at the power/weight of the 12Y-51, compared to the 12z-17, it looks like they took a step backwards Though the 12z stacks up decently against other engines of the period.

1. Probably the best choice.
2. Rather too powerful for period airliners
3. Unless they're really really small a medium speed diesel with better reliability would be preferable.
For a purpose-built diesel I think the power/weight ratio is a bit high at 0.81hp/lb. I'd expect it to be around 0.6-0.7 but higher figures were possible I seem to remember from a book on Aircraft Diesel engines.
Italy is looking at an aircraft/marine diesel based off its highly successful Isotta-Fraschini Asso series that'll bee around in a few years to coincide with some airliner developments. I'll point out that this basic engine has been in production since the 1920s and is still a world leader today in it's turbodiesel form.

2. Twin engined Atlantic crosser? 3000 horsepower, about an 80-100 foot wingspan, speed about 250 knots, 40-60 passengers [sardines]? I thought a pair of diesels might work. Somehow one needs to save on fuel load to obtain the range.

It doesn't look anything like a Mann 180 vee or boxer to me. Its not possible to fuel inject or bury in a wing as I see it.
