On many linux systems, there's the alternatives system.

You can install various versions of perl, and switch to any of those using that; the hashbang remains the same for all (#!/usr/bin/perl). But beware - it is global. Take care to switch back to the defaults before running any system stuff that relies on perl (like apt, cron jobs etc).
