Being able to interfere from elytra to chestplate and vice-versa quickly

There is one thing that annoys players in the endgame of a world when they try to explore, and that is switching from elytra to chestplate and vice-versa, you always have to open your inventory, take the elytra/chestplate from there put it on the slot, etc, etc... But sometimes (a lot of times actually...), we forget to switch and we either fall to our death or take way more damage than you expected. I have an way of improving that or making less annoying and dangerous : See how you can put armor on by left-clicking/"using" when it's your hand? That's my idea, left-clicking/"using" with an elytra/chestplate in your hand should replace the other.
