My question stands not as we would run out of immigrant regiment but what happens when 2 groups want the same name instead of a heap of cannon fodder regiment from NY ( no offenses Irish and blacks ).
I do stand by calling the groups something other than regimet.
I figure we'd do the same thing we do in NW. Besides, what would we do to differentiate.. say, one company of the 33rd VA from another, beyond the company designation? (Some tags in NW are bad enough. 1stEPI/FKI/WPI/WFI syndrome.)
Also, if we became single companies of regiments, the over-representation of the immigrant regiments would be increased tenfold (Literally.).
(Don't take that the wrong way. The Irish, English, Scots, Germans, Poles, Frenchmen, and the men of all the other nationalities that served on both sides were brave men. However, they've recently been over-represented in both games and the study of history itself, at the expense of the histories of the many hundreds of regiments that were made up of Americans.)
