Graphics Interop: Performing texture lookups on formats other than 8, 16 or 32 bits per channel?

Is there any way in CUDA to perform texture lookups on texture objects or references bound to graphics interop textures that have been allocated with formats other than 8, 16 or 32 bits per channel? In particular I’m interested in accessing OpenGL GL_RGB10 or GL_LUMINANCE12 texture internal formats.
