However the OP is talking about producing their own function to generate sequential GUIDs that would not be affected by a restart. The tradeoff of course is that all GUID-generation would require a roundtrip to the database which has its own set of baggage.
Considering that the OP has also identified that the existing GUIDs have been used in "thousands of lines of code", I'm hoping that he won't consider such a thing. It would even break GUI code unless they write a wad of "Instead Of" triggers to covert the UUIDs the GUI code is already passing.
