Yes, combining houses and planets' symbolism is a method you can use to interpret house rulers' placement.
I am not sure resources about this interpretation technique are available on the web. With the exception of some good websites most references are either too shallow or unrealiable. This information is however contained in rather old astrology books, which sometimes can provide extremely detailed interpretations. One such books is "Astrology : Complete Guide to Theory and Practice" by N. Sementovsky Kurilo.
