I'm probably not qualified to answer this because I've never tried. But, I can say that it is recommended that even changing the camera rotation a bit, or removing the scope and just putting it back in the same position can corrupt a T-Point model enough to require a re-synch into the model, or a new T-Point model. It's hard to imagine a SBS arrangement where flex issues due to the focuser, or mirror, or mounting wouldn't be different enough on each side to require different models especially considering the degree of accuracy obtainable. Maybe a model would be usable for both scopes if a high degree of accuracy is not required. I guess one scope would be very accurate, and the other not so. Certainly use the longer focal length scope to get the model...
Furthermore, I think there is a current related post in the imaging equip forum where a user has an SBS system and is unable to guide both scopes simultaneously. If I understand the reasons why this fails it isn't just difference in flex, but also the fact that both scopes may not be exactly parallel to the RA axis, and the fact that both scopes do not have the same radius during rotation around RA. I guess those latter two facts might also influence pointing accuracy.
Try it and tell us what happens!
