That concept has been done, particularly on the Daryl Smith model Kalison and the Hirsbrunner HB2-P. The Kalison has brass slides that have been nickel-plated, and the Hirsbrunner has solid nickel-silver slides( 90% brass, 10% nickel, also known as white brass).
If you have a tuning slide on your instrument that was designed to be a stationary slide and you want it to work fast, I'd suggest cleaning inner and outer slide tubes very thoroughly and then trying Hetman #4 or #5 slide oil and see how it works. If it does not work smoothly, then the slide will have to be fitted and aligned. Where braces attach to the outer slide, there is often a distortion of the tube and the slide binds there. That, and dirt are the two main culprits I see daily in the shop.
