I think with OSPF this will be very difficult to 
do without rebooting (or as long an outage as rebooting). 
We migrated from OSPF to IS-IS and changed some loopbacks a  
while ago, the IS-IS change was totally transparent - no issue, 
but on the change of loopback caused a lot of BGP churn. 
It was easier to change it and reboot and do
it over a period of time in small network triangles. 

I always thought that the billing system was the database
of record ;-)
