VXLAN deployment question

Good afternoon all, any insight on this would be greatly appreciated. I am currently working as an intern, as I retire from Active Duty military, with a local internet transport service provider as they try to transition from a WISP to a FTTH provider. The owner, when I came board is looking to use VXLAN to extend layer 2 to customer PONs from the BNG. With that said, I have run laps of the internet looking for documentation of scenarios where this might work. All examples I find are limited to data center employment between VMs and a server. I am coming up empty.

Scenario is as follows:

Ring network with Fiberstore NS8650-32 acting as spine, distro switches in each area to represent cities would be Fiberstore NS5860-48SC forming another ring infrastructure with 2 gateway switches per city area on backbone. NS5860s would feed Ubiquiti Ufiber OLTs further broken out to Ubiquiti ONUs to which subscribers would connect their home routers.

The desired outcome is for vxlans to separate different Internet service providers in each city. These VXLANs would terminate at a distro switch that supports VXLANs. In theory they would be mapped to a VLAN uplinked from user access switches. Is VXLAN the right answer? Has anyone seen it used in this fashion to connect a subscriber to transport up to a BNG and not in a data center or VM environment?

Thanks in advance for any insight anyone can provide.
