The depth of the seal isn't so much of a factor in me achieving a good seal it is if the tips themselves are wide enough to grip the walls of my ear canals to achieve the seal. I'm also not into ear rape :P. Note the Auvios are indeed a bit taller in size than the JVC and V-moda but not by much at all just as the V-moda and JVCs aren't that much wider. But it's enough so where adding in an extra tip to the Auvio (your mod) still won't work. It'll just lead my ears to getting irritated by the silicone rubbing up against the insides of my ears and still not getting a good seal (oxymoron).
It seems what you're trying to achieve is a vacuum seal, which I can't stand. It's like the iem is creating negative pressure on your eardrum, which hurts on insertion and removal. I think that's also kind of detrimental to the sound. Putting that kind of pressure on your drums seems like it would limit how much they could move and "react" to vibrations. That's why I prefer sawed off, wide bore foams on sealed BAs like the 334, SD3, XBA-3, etc.
