5-axis Milling Machine with Laser for Material Deposition

Hello, community members!

I need to create 5-axis Milling Machine with Laser, plased inside the machine, but called through Tool Change.
What is the best way to create Laser Head? Through Interchangeable Milling Head or as Milling Tool with Representation?

Also I need to create Workspace where Laser could work. It is not travel limits for machine. Is it possible?

Maybe you have some experience in this and could help me.
Any comments will be appreciated.

Thanks, Vitalii.
