Enjoy.
To answer your question, the cab is the same size as the earlier versions so I see no reason for the cover not to fit. If you go for a Roqsolid one, you can send them your measurements and they will make to that size but they usually have a pattern with the standard dimensions anyway.
Re the DI, it is a pain but whenever I have gone through a PA, the soundy has found the socket and plugged it in, they are used to this model.
