Absolutely. There are definitely many ways to do this.
I personally don’t think this is so complicated. My approach is to take the fastest, easiest, and most convenient way to do this and do it at a reasonable cost. Whatever the setup is, the fact that it works does not mean it’s the best option. Workflow and convenience are extremely important. We change designs all the time to account for ergonomics and workflow. Equipment must be easy to use and make the operator’s life easier and more productive. More complex setups may add more time, equipment, and long-term costs. (Not referring to your suggestion, just speaking in general.)
I would not be surprised if the difference in a normal ball and cage pump over our hash pump is under 5%. However, even at 0.5% hash damage, the pump pays itself quickly in a big lab. Savings of 1% may not make sense for a home grower, where you would just opt to purchase the cheapest pump possible. @SubstituteCreature has a system that works for him and many others must have innovative ideas that are cost-effective.
