Reasonable is a relative term.Does this seem like a reasonable way to get four fixtures in a long journey without running 3wire the whole length?
I never run the travelers thru the lights. Too many extra splices and you have to take fixtures down to troubleshoot.
2 wire power at one end, 2 wire switch leg at either end and 3 wire between them is the way to go. Nothing in the fixture boxes except the switch legs.
