Is there a way to scale down my character for old content?

Hello, I've been trying to enjoy older content such as quests and the like. I'm mostly in it for the stories and the occasional transmog. However, I find it kinda stale to mindlessly one tap every quest mob I come across.

Is it possible to scale down a level 80 character so that my gear and level would be level and gear appropriate or do I have to make a brand new character? I already tried Chromie time but she kept blabbering on about the Radient song. Thank you!
