a while back we were discussing possiblity of other unit lines, and concluded it was best to leave VP's melee/range mix untouched. I'm still mostly thinking thats the way to go, but I've had some more time in-game to reflect on this since.. just got to industrial in a naval-heavy game w/ your EE-VP mod conversion.
I really like how the 'ship of the line' shows up as its own same-but-different melee weapon in the age of sail in that mod. I wonder if the dreadnought/battleship shouldn't get the same treatment here, but as the modern ranged super-weapon, somehow distinct from the cruiser line. I think there are a good number more models available to borrow from for another cruiser or two.
Also thinking of breaking the zeppelin out of the recon line, and making it into its own naval/land hybrid.. thinking dirigeable (current model) -> zeppelin (ww1 model) -> airship (ww2+ model) -> naval helicopter. (also will have to replace industrial recon w/ a transitional recon/combat land-unit.. thinking a "sapper" role)
Do you have any appetite for doing any more development here along these lines? if not i may build another add-on of my own....
