I will admit that I'm struggling a bit here, because I'm having trouble coming up with a coherent mental picture of what a legitimate alternate hypothesis to Occam's razor would actually look like.

In fact, if you take my hypothesis to be true, then Occam's razor would still fundamentally hold, at least in the simplest form of "a less complicated theory is more likely to be true then a more complicated", since if "theory-space A" is smaller then "theory-space B", then any given point in theory-space A is more likely to be true then any given point in theory-space B even if the answer has an equal chance of being in space A as it does of being in space B. So I think my original hypothesis actually itself reduces to Occam's Razor.

I think this is where I just say oops and drop this whole train of thought.
