The HE hack targeted EVMs, Layer 2s have never been targeted and doubt they ever will be. More coding would need to be done for the distribution from a local source, but not impossible and in the long run, way cheaper. It would not be able to harness any kind of LP rewards except what you coded in for providers, one would still have to be present on the side-chain Hive Engine exists on for people to trade it and fund the pool.
