Could I run WAN traffic over VLAN?

A manufacturing shop has 2 offices, and 1 rack in each office (MDF and IDF) with a 180’ fiber between them. The ISP coaxial cable enters the building in the IDF closet and runs 180’ to the modem in the MDF. The modem can’t bond upstream channels from the MDF closet, but can from the IDF closet.

The key is to minimize the coaxial cable length, and moving “everything” to the IDF is not an option for this morning. I want move the modem to the IDF, then configure an extra port-to-port VLAN between the two switches (from the modem in the IDF to the router’s WAN port in the MDF). Would directing WAN traffic over LAN equipment cause a security issue even if it was in its own VLAN?

And thank you in advance )

(If this doesn't belong here, please don't delete, let me know so I can move it to another sub)
