Other than that, it just can't happen.
Remember, what you should focus on is this:
1) Did X god give a portion or all of their body to create Mundus?
- If yes, it's an aedra.
- If no, proceed to question 2
2) Is X god living in Oblivion?
- If yes, it's a daedric prince
- If no, proceed to question 3
3) Is X god living in the Aetherius?
- If yes, it's most likely Magnus, otherwise the guys who followed him are known as the Magna-Ge. To note, Merida used to be one of these, till she consorted with "illicit spectra" and was cast out by her father, Magnus, and now resides in Oblivion.
- If no, then you have something like Trinimac (pre-Malacath), Talos, and, possibly, Shor/Lorkhan/Shezarr.
