I hope Nereid doesn't mind me jumping in here, but a test for Lorentz invariance, here on Earth, would detect a violation. Since, in your model, the Earth is not stationary WRT the aether. A test taken over several months, as the Earth moved through it's orbit, with the apparatus having a fixed orientation to Earth, would detect a difference in the measurement of the SOL, as the apparatus changes it's orientation WRT space. If you correct this by saying that the aether moves along with the Earth, then you run into the problems of aether drag, such as stellar aberation, violations of Snell's law and the fact that there would be different amounts of aether drag for different frequencies of light.
And, just for your reference,
this test happens to fit the bill. Notice that one arm of the test was fixed east-west and the other arm was perpendicular, straight up. With contraints on a violation at 10
-13 for velocity independent terms and 10
-9 for velocity dependent terms.
