"Doubling" with upright & bass guitar has been a thing for quite some time. When a musical director wants that, I am more than happy to oblige. I can switch pretty quickly – I've never held up the next song, or imposed any restrictions on the set order. (The way some guitarists seem to like to do.)
For the Salsa band, I like to use a hollowbody for the old-school material and an active 5-string for the modern pop stuff. It's not absolutely necessary, but it's not that big of a hassle, either. (Actually helps keep that heavy Warwick from wearing out my shoulder.)
I often prefer to keep things simple, and use one bass for the whole set. When I bring an extra for backup, it can be fun to switch those out between sets. Variety is good.
