Yes, thats exactly what you would do.
BTW, after your last post, I updated the utils script to add a "createHull" function. Not having that function was an oversight on my behalf (I guess I was just too excited to get it out to folks!)
You can snag the updated version here:
One last thing, if you don't delete your history, that mesh will update as you move your object around. If you do delete your history, you'll lose the dynamic updates, but the resultant hull will still be cached and saved in the mesh nodes.
Let me know if you have other questions or feedback (or if you want to contribute)!
