My choice, which is weird.
Kohan cross Granado Espada (for the artstyle)
Would have Kohan-style gameplay with a Baroque-style art and units, along with magic. It the game had Stardock-level AI, it would be a masterpiece.
Console pick: (this is going to be really strange)
Virtua Fighter cross Buriki One
One of the most strategic games ever (yes, it's a fighting game, but it is very very strategic) which lacked some soul, combined with an obscure SNK franchise, which would be suitable to that style of game, yet had characters with plenty of soul.
