That would be great!
I think that it might be most useful (others are welcome to share their opinions, of course) to include both the original and the roman characters so as to maximize its helpfulness whatever text the reader might be working through. I might be well, too, to allow for notes to acknowledge or explain inconsistencies, contraditions, and continued mysteries, as these will be inevitable and either the product of how difficult it will be to obtain difinitive information, changes of usage during the period, or differences of usage within a national military or among different ones.
Many thanks :o)
