I guess it would work if there is some kind of force that leads some timelines to go out of existence or converge back towards heavier nodes, something like a neural network structure.
If there were two opposing forces, always exponentially self improving towards maximum efficiency in two opposite sides: 1) ordered/creative/perfectionist/preservative/etc, 2) chaotic/destructive/disruptive/etc... suppose our universe sits roughly in the middle of these two, does that not seem to explain where we are?
Also, given the seemingly limitless propensity of the universe towards balance, and its apparently limitless capacity in both regards, it would seem natural to infer that both forces keep going in ways beyond that which we can directly observe.
Intuitively, certainly, it seems very right. Of course, it also gels very well with countless esoteric/mystical beliefs going back eons as well.
