The cap stem won't fit through the housing. If you replaced the Alps stem that grips the cap with an MX cruciform, the switch wouldn't be able to activate since it wouldn't be able to be depressed. The only way to do it is to redesign the slider and housing or to make an awkwardly tall slider.
Yes, but I wasn't responding to the impossibility. I was responding to the genius who said "the popular option isn't always the best one," which is irrelevant at best.
