I doubt that this will do the work proponents require of continuous infinites of worlds (branches/copies). Your "very large number" will eventually run out or, at least, be depleted to a sufficient extent that you can no longer accommodate all ratios.The splitting of worlds is ubiquitous and goes on all the time. How many splittings have there been since the big bang? In either case, the move smacks of desperation!
