Geralday has one or two but I don't know how they compare to the P2 Lo figures in terms of size. What I've seen sold a lot are "cutouts" - I don't remember the technical name - basically just 2d transmapped images on a plane for this type of application. I think that Dosch among others sells these but you could easily create them in Poser. Other than that, I suppose you could take P3 or P4 figures and run them through a polygon reducer. Whether that would work depends on how close up you need them to be I imagine. I think VizUp will even let you select the area(s) to reduce and IIRC, it retains the UV mapping.
