After putting down Robert's Rebellion as Rhaegar and inheriting the Iron Throne, I got the event where I could convert to R'hllor. I did, and all of my children born after that also worship the lord of light.
However, my first two children, Aegon and Rhaenys still worship the Seven, so I decided to marry them off to the Lords Paramount to get some allies because I figured they wouldn't want to marry the R'hllor worshiping ones.
Yet, I still get the "X must not marry an infidel" reasoning behind it, presumably because Rhaegar himself is an infidel. This only serves to remind me of my earlier Greyjoy game where I got the same prompt, despite the fact that the Drowned God is Westerosi in origin.
I don't know if this is an intentional result of design, but it does make playing as members of other faiths somewhat less interesting in Westeros.
