I can see MCH having a res being within the realm of possibility, it is the gadgeteer after all. But I'm not sure if any non-magic jobs should have a res period since it complicates things on how to balance it on a different role which don't use the same resources needed for a raise. Frankly I'd prefer to see MCH's utility shift towards mitigation and or debuffing. (as it once was in Stormblood)
Aesthetic wise however, it would be hilarious to go up to my pals and shock them wide awake. Just as much as it is fun to shoot people in the face as Gunbreaker to protect them.
