There wouldn't be much point in this unless you had recognizable UFC and Pride fighters, would there? The whole excitement of the Pride vs. UFC debate is the issue of which league has better fighters - not which league has better rules. So if you use no-names, it becomes a question of how to compromise on the rules, which really isn't that interesting (to me, anyway).
But if you could set up a series of UFC vs. Pride fights with fighters I know, I'd watch that in a heartbeat, regardless of the rules used.
