Sure .... Tho not a desirable material for the task, it would work IMO.

It will:
Be HEAVY
Run VERY HOT
Resonate poorly because of it being fairly soft.
Will Anneal where really hot and work harden where it flexes.

What would be better?

Just like in commercially built pipes .... Sheet mild steel #1 ... Spun Aluminum #2

How would u make that work exactly?

Sheet steel is cut too shape and rolled into cones of the desired angles, welded together to get the final shape.
Aluminum either cut from billet or force extruded into the shape desired.

sounds like you really are lacking in the basic design education on the subject of witch you ask about
