If you mean that this could be implemented, then great I'm all for it. From a technical perspective it doesn't seem like it should be difficult. I'm under the impression it doesn't exist most likely because the banks don't want it to. Hence the benefit of using cryptocurrency.
Since ACH reversals happen so rarely in the US and since the US dollar is stable there is not much incentive to get paid in crypto. Also, there are disincentives, since the US taxes it as property. I'm definitely not arguing that. Only pointing out that what a pain ACH reversals are when they do happen and how crypto doesn't have that problem. Make crypto more stable or easier to convert from/to fiat and I think more people would opt to get paid in it rather than the current direct deposit ACH structure.
