Okay my brother, it appears a user would need to be in some type of cross with the Shinju, which is understandable. Shirou, like Shingi, passively absorbs the chakra of a tailed beast...and not his Spirit Guides, but instead something more direct. A child of the Shinju born through the Ten-Tails Fission. Shirou can't exactly become the beasts full Jinchūriki for his own reasons, but instead uses the beasts' chakra to his own.
