This idea sort of has been talked about in other threads but i think it needs its own.
EDIT:Each UU would be in groups seperated by Culuture so culuture groups could have the same UU sometimes but for example england could not have a indian or chineese UU
Also these Groups would include Air Units and Naval Units
Have a group of UU that can possibley go to any civ-one for each civ each era besides ancient era-and depending on location production rate amount of accessable land, and number of wars. Each UU would be determined by the stats in the previous era
So if in the ancient era you were very war like you would get a offensive unit in the medivial era and if you were peaceful in the medivial you might get a defensive unit
Lastly i think this should be put out there should be more Naval UUs espically modern naval UUs
