Yes, like I mentioned in my initial reply, it is possible to control servos wirelessly with systems using a Maestro. However, you will have to build that system yourself; we do not have a straightforward way to accomplish it, and things get more complex if you want to use a PlayStation controller as an input, too.
One way people can make a wireless system is to use a pair of Wixels, which are general-purpose programmable modules featuring a 2.4 GHz radio. The Wixels operate at 3.3V, so to use them safely with a Maestro, which operates at 5V, you would need to use something like a logic-level shifter. You could then send TTL serial signals to the Maestro to get it to control servos. You can learn more about how that works inside the "Serial Interface" section of the Maestro's user's guide, which you can find under the "Resources" tab of its product page.
