You may discover that with a new horn you need to change the mouthpiece... but not for the reason you suspect. Different horns will have the receiver adjusted differently and the end gap can be critical in obtaining the desired accuracy of intonation and sense of resistance, or "impedance". THAT should be the primary reason for changing mouthpiece... it has to do with the shank of the mouthpiece and matching the backbore size/shape up with the characteristics of the leadpipe and has virtually nothing to do with the diameter/depth/shape of the cup.
