Certainly is doable.  Take 4 normally open, single pole reed relays,
connect one side of each reed together, stuff them into a package, and
you have a SP4T switch.

HP loved little relays, they put them in a lot of gear.  Relays are
reliable, very low on resistance, very high off resistance, and switch
quickly enough for light duty applications, such as front panel controls...
