Council of Elrond

If, as a FW, I have a non-scout character with the Magic Ring of Stealth and the Magic Ring of Guile, how do those Rings' abilities work?

For example, can I tap Magic Ring of Stealth to cancel a strike because Magic Ring of Guile makes the character a scout, and then tap Magic Ring of Guile on the same turn because Magic Ring of Stealth makes the character a scout?

I think that it works like doubling of CP of one source coruption as effect of The Balance of Things. Such designation, which source of coruption will be doubled is not permanent. Otherwise character losing designed source of CP would be unaffected by The Balance of Things

Similarly designation, which ring gives skills and which ring gives special abilities is not permanent too. Otherwise character losing ring that gives him skills, would be able to use ring that gives special abilities.
