The reason I really want to have the information on a 1 (or 2) component texture is I will be reading it back to the CPU, so avoiding the 3 (or 2) extra components will make the readback a lot faster.
You can just read back single channels, e.g. GL_RED or GL_ALPHA

Oh, so simple it didn't come to my mind. Can this be done together with PBO's?

Thanks a lot.
