As Albert said, it would have the benefit that other viewers would be able
to display it, or okular could be use the rendered formula on systems where
there is no latex installed. 

Since we would also store the latex code used to generate the formula, there
would be no problem with adjusting the color, font size, etc.

HOWEVER, as Albert said, currently poppler (the pdf library used by okular)
doesn't support saving annotations back to the file. I think there was a
GSoC project to implement it in poppler, but I have no idea how that went.

So, until this is supported in poppler, I think Albert's approach mentioned in
#6 would be the best way forward. Although personaly I would probably default
to rendering the formula and showing the code on click instead of showing the
code and rendering on click. This is, however, for Albert to decide, I think.

I would be willing to help you with this, however currently I do not have much
spare time to work on it :-(
