EL- Wire Suit Design Help

Hey! So I’m working on that mock layout for the el wire lengths and such, but another thought occurred to me while I was drawing out the suits sketches. Can I have a pin on one lilypad turn on, while connected to a pin on a different lilypad, and have the receiving lilypad interpret that as a switch? It would free up a large number of pins if I had a different arduino controlling the LEDS, while the main board is controlling the EL Sequencer and other things
