OSPF Recommendation

I'm looking at setting up OSPF between two switches, and am thinking about putting the point-to-point OSPF link *inside* the /24 that is being advertised by the edge switch.

So:

192.168.1.0/24 is the range I want to advertise from the edge switch up to the "core".

I want to use 192.168.1.248/30 as the OSPF point-to-point link IPs. With 192.168.1.249 on the uplink switch, and .250 on the edge switch. 192.168.1.0/24 is VLAN 10, and I'm going to make 192.168.1.248/30 VLAN 15.

I can't find anything that would suggest this would be a bad idea, but does anyone see any problems with this? I'm trying to avoid dedicating another public IP range just for OSPF point-to-point links, and I want to keep the "core" switch out of the 192.168.1.0/24 VLAN / IP range.
