You need to stop asking us for validation of your sound concept. It seems as if you've given us examples, in the youtube clips, of cornet sounds you like. Fine -- those prove that there are players out there making sounds you like on the instrument you like, so what more validation do you need?
The one thing I will point out is in this clip:
Victoires du Jazz 2013 - Médéric Collignon et le Jus de Bocse - Hommage à King Crimson - YouTube
the sound of that Getzen cornet is being processed through a lot of effects. What we're hearing (and I'll admit, I couldn't make it to the three-minute mark... what that guy plays just doesn't appeal to me) has very little to do with the "real" sound coming out of the bell.
