There's no inherent problem with defining measures on uncountably infinite sets--for example, a bell curve is a continuous probability measure defined over the infinite real number line from -infinity to +infinity, which can be integrated over any specific range to define a probability that a result will fall in that range. But as I've said, the problem is that although you can define a measure over all frames in relativity, if it looks like a uniform distribution when you state the velocity of each frame relative to a particular reference frame A, then it will be a non-uniform distribution when you state the velocity of each frame relative to a different reference frame B, so any such measure will be privileging one frame from the start.
