If poppler is just using fontconfig + freetype2 for local font 
discovery for to-be-opened pdf docs (this is my current understanding),
then that would be only about as useful for pdfTeX as that same code
in xetex already is. And that is not very much, I am afraid.

OTOH, if poppler is not only a pdf rendering library but also a pdf
creation library (or aspires to become that, then it is quite likely
that there will be some overlap that could possibly be merged one
way or the other.

I do not know enough about poppler (or about pdf in general, for
that matter) to say something definate about this, sorry. I never
have had to anything with the pdf image inclusion, so I am not a
suited person to respond about that part, at all.
