As to your question. It's not possible without hard coding it into the module to force specific skins. Edit Controls that load by themselves always load using the admin skin. Some developers load controls dynamically so that the page skin is displayed instead of the admin skin. The advantage of doing this is that other modules in the page are not hidden as when the admin skin is loaded.

You could add settings to your module where the user can select a pairing of <module control >- <skin>
