Hey Josh,
A double crossover, for what it's worth, will allow you to continuous run one loco on
all track on both loops without throwing any switches. (Assuming you have two loops,
of course.)
You should be able to take a bit off the the switches also, I have done that on the traction line more than once.
Just cut a bit off the road bed and rail where you can with your dremal tool and then make allowances for the slide connectors.
