I say try it and find out. Many Catholic magicians, or magicians who converted, say the spirits notice and are more respectful if you are baptized.
Not saying convert, I was not originally a "believer" and only did so becasue of some amazing and extreme Catholic theophanic manifestations , but the daimons sure seem to snap to. (I think it's becasue of the manifestation of the Demiurge we have locked in the Vatican basement. Heh!) That said, I'm still a Pantheist and say there are many ways to get to the same place... PGM Headless Rite, etc.
But really, has nobody else noticed that pretty much all of traditional Western magic is essentially Folk Catholic and Eastern Orthodox (Folk Orthodoxy)? Are people not aware that most New World Sorcery is Folk Catholic across the majority of the entire Western hemisphere? Every Haitian Vodouisant and Mexican brujo is Catholic, or grew up Catholic.
We wouldn't even know about the pagan philosophers if it were not for the Catholic love of the Greek pagans. Other historical Catholic magicians include: Marsilio Ficino, Cornelius Agrippa, and his teacher Abbot Trithemius (who was a Benedictine Abbot). There was also Giordano Bruno, Paracelsus, Johannes Reuchlin, Athanasius Kircher, Tommaso Campanella, and others such as Benedetto Rinio , who was a 15th-century Venetian physician and scholar who compiled massive herbal grimoires.
