Yikes. I would try to offer some suggestions but it would take a lot of conversing about the different cues that are already there as I ride western and know nothing about dressage. You might want to PM a member here named Spyder, there is also one named ~Anebel~. Very knowledgeable dressage people, one of them might be able to offer a few suggestions that would be feasible and practical for you.
Edited to add: Sorry, the second member's username is ~*~anebel~*~. There are also several others that are very knowledgeable, those are just the first 2 to come to mind.
