People have crossed Euvitis and Muscadine grapes, but the success rate is very, very low. Although I can't recall the exact background, 'Southern Home' is a hybrid of Euvitis and Muscadinia, if I remember rightly.

I'd like to hear of anyone who has worked with Lincecumii as a hybrid vitis plan. I am using V. Coignetiae and have had some good results locally.
