If Gaara had earned Shukaku's full cooperation, he'd have been stronger than he was during the Fourth Shinobi World War, but I don't think he'd be at Kurama Mode Naruto's level. After bonding with Kurama, Naruto could overwhelm five tailed beasts by himself, barely needing Killer B's help. Even if we were to say that the Six Paths jinchūriki couldn't unleash the five controlled beasts' full power, Yang-Kurama still kept up with them. Gaara's prowess with the sand was comparable to Shukaku, as his father initially thought that Gaara was using the Feigning Sleep Technique. If the two joined forces, Gaara would be able to use Shukaku's cursed seal markings and Magnet Release, but that's about it.
