If the Qabala speaks to you, explore it, work with it. I have known some Setians who've studied and worked with it, as well as, Thelema and other works of Crowley. The Temple of Set is multifaceted in its exploration of the Magickal realms.
Kabbalah can work with anything, but while 777 is an impressive work there are many problems, and it's really no authority on tree of life correspondences. I always say make your own correspondences.
