I think this game already gives you this as long as you gear matches the level you are down levelled to you are good to go! I gear depending on the zones I am in, going up through them in as sending level order, and ignore my real level altogether for a nice relaxed levelling experience.

This is not necessary. You can just stay in lower leveled areas and the game will downscale your power so that you’re not just trampling everything, while still giving you somewhat adequate loot. Just do whatever you want to do and don’t worry about over-leveling content.
