It might be worth trying, but essentially what you're trying to do is cost/load sharing on the aggregation system. You could do that by computing indexes and sharing them around, to reduce some amount of required compute, and I suspect we'll be doing things like that. (For example, having the precomputed follow graph index as a separate dataset.) However if you're trying to replace the full operational system, I think the only kind of load sharing that could work would require federated queries, which I consider a pretty unproven concept.
