Why not render to an image and create a sprite using that image? Then you can make the sprite any size you want. Please be aware that render images are required to be power of two in size on Android and possibly other platforms so what you make on Windows may not work on mobile without some tweaks.

The default render quad object does exactly that for you already, is there any reason why you cant use that?
