mulberry grafting

Can you graft any mulberry variety to any other?  Specifically I want to graft Gerardi to dwarf everbearing.

I'm not too particularly knowledgeable on this specifically, but it shouldn't be a problem- If you can graft pear to apple rootstock, you should be able to graft mulberry to mulberry. Unfortunately I have only tried water rooting of a non-fruiting variety.

Having grafted a few mulberries, yes, it is possible. However it is a bit tricky, as mulberry produces a lot of sap. Some grafting techniques and times might drown the scion. I have grafted successfully in pots, before they go into vegetation.
There is also a technique I haven't tried, which is said to be specifically for grafting mulberries without drowning them.
