Very tough question. Lots of variables involved. I wouldn't think any of the singular variables you list causes the 'slipper' partials, but I'm not a vibrations / sound expert. One thing I will say is that there are horns that slot very securely to double C and beyond, and they are typically built with that task in mind.

Consider visiting Nick Drozdoff's website - he's a trumpet-playing physicist who loves questions like this. Another resource is Dr. S.W. Theil (Thiel?) - another trumpeting scientist, on staff at Indiana University (I think.. my apologies SW if I cited the wrong school).
