Any new allies to the Crystal Gems?

I was thinking and after the hardly won victory over Peridot and Jasper This yellow Diamond fellow isnt going to be ignoring The crystal Gems any more,so the real question is wheres backup for the Crystal Gems??? (there are 4 Crystal Gems and probably a army of homeworld Gems i have some ideas for new Gem Races also),i dont know if its my perspective of things or do other people see it this way?,i mean Yellow diamond sounds like a big deal because peridot is still on the loose and shes like a walking gem mobile so he/her must know by now right?...so yeah if you like this idea then tell me how to improve this thought i love suggestions,so please dont hesitate to ask or critisise. :D
