The main difference between a record made with the amp + microphone and the profile is the room reverb.
The room reverb affect the global EQ of the profile but that's all.
If you are able to set a reverb simular to your room reverb you will be able to get exactly the same sound with your profile then with your classic audio chain amp + mic record.
Why not let the Kemper send some test tones after the profiling process in order to get the main characteristics of the room reverb then set up automaticaly into the RIG a reverb programmed with these parameters.
So basicaly after the profiling you will have the bloc amp and the reverb bloc set up.
I think it could increase the result and gives to the Kemper the 5% which are missing to be perfect.
With no doubt it's already doable.
