Don't know if it would simplify things for you or not, but I control my landing lights with either the retracts or the flaps. Depending on the plane. Usually the flaps. Then use a single 3 position as kind of the master switch. Off / nav + strobe / landing. When I get ready to take off I just put the switch in the 3rd position, and it stays activated the entire flight until the taxi back when I can turn the landing lights off by going to 1st or 2nd position.
Just a thought
