Hmm... well that's one way to get around the upper limits of mass problem.
Hopefully there are other solutions. Like lots pumping your mass as large as you can go, getting a lot of food and exercise at the new size, and then pumping it higher once you mass naturally increases underneath the cloak.
...mind you, given that under the "cloak" they are all animals, that might not be a solution at all, but I'm holding out hope.
