As far as I know no one has yet made up a stick mount for the 2808 series, but what you could do is buy one for the 22xx motors as a pattern, and make a new ply plate for the front of it:

I have my 2808 mounted in a slightly modified "Aeronaut Horizontal mount for Speed 400" (HLAN 2097) - it would be easy to attach (screw) a ply plate (about 40mm x 40mm would be ideal) horizontally atop the SS stick, then attach the beam mount to it with the standard four screws.
