Goku has already transformed into Super Saiyan Blue multiple times, isn't that just the SSJ version of SSG? If I'm not mistaken, he once said that he learned how to control that power after (or during) his fight with Beerus.

Vegeta achieved that transformation just with traning, now that's a mystery that might require an explanation. But I don't see why Goku would need people to hold hands to transform into SSG.
