OSPF on a single subnet versus dedicated links

At the moment, I have a handful of devices, each have an IP in a /24 subnet. This /24 subnet is like a WAN subnet. They have static routes to route traffic between them. We're starting to add more devices, get active/standby devices going, etc. This doesn't fair well with static routes (doing fail over between them is manual or IP SLA and is messy).

​

I'm wanting to enable OSPF between these devices.

​

Any reason why I couldn't just enable OSPF on these interfaces and call it a day? (Removing the static routes afterwards)

​

Would I need to instead, remove the /24, designate one or two devices as "cores" and then create /30 links between each devices and the cores?
