Cross drum resonance is gonna happen. Usually no matter how you tune you will end up with one drum reacting to another somewhere.
As Professor Jr said, you have to experiment with positioning for that comfort zone. No, you won't find it in a day or so. Probably talking months, if you are lucky.
Just play. If you find yourself reaching or twisting to the point it feels unnatural, try repositioning one item at a time. Note: One item at a time.
Above all: be relaxed and enjoy.
