For a start, I'll only list the province names, such as they are, that should belong to HRE. There are further provinces to south and east that were part of the crown of Hungary, held by Hapsburg emperors - not part of HRE, but also not Ottoman.
Kaernten - Carinthia:
Steiermark - Styria:
Krain - Carniola:
There are also provinces that are shown as part of Republic of Venice, but should also belong to Austria and HRE:
There are also many geographical problems, provinces not located where they should be (Velden and Voelkermarkt, for example, should clearly change places), and the inconsistency of naming - IMO, names should either reflect the historical situation (German) or present (Slovene), but not a mixture. Not to mention Caporetto (Italian) fits neither. Furthermore, I think names should be given after towns that were important in the 17th century, not today (like Trbovlje).
If there is any interest, I'll go into more detail, but I don't want to spend a lot of time for nothing, if my suggestions are disregarded out of hand, for whatever reason.
