Long long ago, some gaming magazine did a whole article about Voodoo in Shadowrun (maybe back in the 2E days?) which included "voodoo zombies" (as opposed to "nuclear zombies" or "virus zombies" or what not). Basically a specialized summoning requiring a prepared vessel, which was eventually folded into the paradigm, more or less, with "possession" traditions.
That said, there is a long standing tradition of one-shot, basically unique "WTF?!" in Shadowrun fluff, things that can only come about with a liberal application of plotdevicium. Even in adventures, come to think of it. And of course, even if it's not actually possible, a little stage magic can convince your players that it is.
