Anybody ever cut a cornet to C?

Working last night with a fine cornetist who collects and plays Conn Victors, it occurred to me that I know of several others who use(d) the same horn, including Bix & Max Kaminsky. The distinguishing feature of the Conn Victor is a secondary tuning slide after the valve section which features two rather sharp right-angle bends in the tubing and a screw adjustment. Nobody seems to know the purpose of that extra tuning slide, although it may be a vestigal remnant from the old high-pitch-low-pitch rotor that was used on some early instruments.
So I was wondering what would happen if one removed it and replaced it with a straight pipe? You would end up with a cornet in C, and it would be one of the best ever made. (Of course you would have to adjust the valve tubing lengths.)
-Has anybody ever tried that?
-Would anybody WANT a cornet in C?
-Perhaps a CC tubist who doubles would find it useful.
Cutting a BBb tuba to CC seems to triple its resale value, in spite of the fact that its intonation is usually messed up.
What would happen to the value of a Conn Victor cornet if it were cut to C?

Very interesting...Thank you for the history!
