Toward Ecosophy

I'm working with classic golden dawn material, and am planning to add the Rose Cross to my daily routine. I already have the LBRP and Middle Pillar, and am trying to work out the best spot for the Rose Cross. Could I add it between the LBRP and Middle Pillar, and use the divine light called down during the Rose Cross to formulate the descending energies of the Middle Pillar?

Are there any concerns with doing this?
