Nope, not really.

Steven can't teleport himself in a bubble, he needs to be outside (We assume so unless the show has hinted that it's possible to teleport from within a bubble). Lars can't go inside his hair, so he cannot go with the rest if they went inside his hair.

Once Steven teleports Lars and the rest of the Off Colors into the Temple, they literally have no way to get back to Homeworld. At least if Steven and the Off Colors went inside Lars' hair, they still have a way to go back to Homeworld.
