Sure. But instead of giving you something that is beyond many in this thread, I will give you the following argument from Charles Fort: After spending many years searching newspapers, he was unable to find a single report of stars crossing in front of each other as seen by astronomers. The distance to stars and speed of light does not matter. If the earth is going around the sun, and get 186 million miles from whether it was 6 months ago, and if stars are at various distances from the earth, stars must be seen to cross, it is a question of geometric parallax arguments (Try walking from one side of the front of a room to the other, and keep your eye on two chairs at different lengths from you). His conclusion was that stars are not "hanging" in space at various distances, they must be painted on some kind of canopy and thus all the same distance from earth. So if you can find a case of stars appearing to cross that will settle my doubt. (I just tried a google, and could not find anything). If you cannot, this constitutes presumptive evidence that the whole measurement of star distance differences is in error, and consequently, anything derived from it (including the speed of light in space) is wrong.
