Looping is best handled using Value Clips in USD. Use the Geo Clip Sequence LOP in H20 to (relatively) easily create a value clip with looping animation. Then reference this value clip looping animation as a prototype to use in an Instancer LOP. This will give you a point instancer with all identically timed looping animations. Then use a Retime Instances node to assign different offsets in the animation to each instance.

If your shot goes from 1000-1500, you should be fine to create a looping animation of length 550, then make sure all your offsets generated by the retime instances LOP are in the range (1000, 1050). Of course with value clips, generating a loop that is 1500 or 15000 frames long should be no problem, and won't affect the size of the USD much at all.
