I would worry media woud get in the primer. I have tumbled hundreds of rounds of live ammo. The vibratory tumblers won't generate enough punch to dent a primer enough to fire. So I would load then tumble. One othe suggestion would be to decap the primed brass, tumble the un-primed brass, then re-seat the primers. I do it with a decapping die. You just have to move a little slower and press softer than if you are using fired brass.

nah, I'll just resize, expand and load. I ain't decapping 1000 live primers
