The way the high mu section of the 6EM7 is set up now, it has an in-circuit gain of 51. By eliminating the cathode bypass cap the gain will drop to 25. Not only will this achieve a gain reduction by 6dB, but it should also quite nicely reduce distortion from the degenerative current feedback. You will be eliminating a capacitor that's in the signal path while getting your reduced gain along with improved distortion in the process, a nice win-win IMO.
Even if you go with an additional input tube such as the suggested 6SN7/6J5, it would be very simple to try what I've described here. It would only require a couple solder connections and at the very least it should be a good education.
