Possible to Add Index Gallery To Bottom of Pages?

Does anyone know if it is possible to show a full index gallery (like the homepage of a portfolio website) at the bottom of each secondary page, instead of the preset "index navigation" that is standard in the Jasper Jin Template?

Instead of seeing the written projects, I would prefer that viewers scroll and see the full index gallery again. Possible with CSS? Template hack? Let me know your thoughts, thanks in advance!
