Multiboxing Legacy Raids

Hey I have a question regarding multiboxing legacy raids, is it somehow possible to multibox 5 chars in 5 different raid ID´s at the same time ? Like navigating them via repeater so you actually have to clear the raid once but have a x5 chance on the mount drop for example.

Mechanically, yes, it's possible. It's a headache to be honest.
When I do it, I usually just do it in phases cause they will always get out of sync in terms of direction/movement.
