I would do the following in this instance: 0) Make sure all your devices support CIDR (this is what you are doing) 1) Subnet the management lan into smaller chunks and assign one chunk to each remote site. You need this for routing. 2) At each site, bring up a vlan for the assigned management lan section to keep mgmt traffic segregated. 3) Make sure to update your routes and firewall rules accordingly. 4) Might want to look at a dynamic routing protocol if you're going to be changing this type of thing often.
