Wallydog,
Sounds like you have found a way to continue shooting. Continue experimenting,there is really no right or wrong. Accommodations to physical difficulties is necessary and in no way impairs the opportunity to excel. Cross dominate is not a "show stopper", just a speed bump that can be overcome.
To be more help, as ALWAYS, I recommend FORM improvements. Video of your current shooting allows us to see where you are and possible suggestions from there.
