So using the blind people and elephant technique of figuring out Getimians...

Consider a pair of twins, one goes on to exalt as a Sidereal, and the other exalts as a Getimian: Is this even possible? And if so, what's the potential for drama in that scenario?

(Side note, I will never not be able to call them the Gentlemen Exalted in my head....which is probably an Exigent idea I should write down)
