Yes, but how do you do that with existing, commercial recordings,
which is what the OP was asking about?

The simple solution is: If it ain't good, don't buy it! "Remastering" a
bad recording won't give you a good recording, remastering a good
recording will often give you a bad recording.

How do you replace a poor recording of a great performance with a good
recording of the same performance? I don't think even Albus Dumbledore can
do that.
