There are certain humans who are powerful enough. Macgregor Mathers required 2 bishop pieces to be reincarnated because he was a very experienced and powerful magician. If the person turns out to be very powerful then it's possible. And it's clear that Heaven is really selective. And plus there are limitations to being an angel which would make it basically impossible for any non-human and non-believers to be reincarnated as one. Well not that they couldn't be reincarnated, but they wouldn't want to.
