Nomad federation using consul connect gateways

I have 3 consul datacenters connected over mesh gateways, and I want nomad to be there as well( really just for job forwarding I think). My understanding is that using built in nomad federation requires network access between all of the server over wan. I was going to use something like nebula or headscale to achieve this but before I do I was wondering if there was someway to use consul gateways to do this without getting a second overlay network involved. I dont think Nomad can do this by default according to git issues.
