No, I don't think so.
In order for the career scenarios to be fair and competitive to each and every player, they must play out the same for everybody, everywhere, anytime.
So you'd better change them to standard in order to use different physics.
Mind you, the scenario preserves certain control parameters, so when your new physics alters these, the result might still not be what you expect.
In order to complete erase these preserved control parameters, you'd have to create a new scenario.
I know because I ran a thread here with the EQ pressure needle being stuck on the F59PHI because of that preservation. It only became unstuck if I uncoupled the locomotive, and got stuck again the moment I coupled back to the train.
