It would be nice to ride with the BR 182 as an IC train and drive it 200 km/h and it gives us more variation to drive the train and on routes.
The BR 182 is more of a backup for IC trains, can't remember them ever being on a connection by plan. I've seen pictures of them running near Duisburg with ICs though, so the ability to sub in a BR 182 on any random IC service, replacing the BR 101, shouldn't be to unrealistic and would definetely be fun.
Option 2 for DTG is reskin the DB BR182 into the ÖBB1116 most people from Netherlands will recognize it as the locomotive that comes from Schnellfahrstrecke Köln-Aachen to run the Amsterdam Utrecht Arnhem Oberhausen Duisburg Wien/Innsbruck sleeper trains from Köln Hbf
