Yeah, you could probably do it, but...
When they designed your sail, they designed it for 2 reefs. If it had been designed for 3 reefs, the first two probably would have been placed differently. So if you add a 3rd reef to your current sail, it may not be in an ideal location -- it will probably end up reducing sail area too much.
Or maybe not. Maybe they placed those first two reefs no differently than they would have if the sail had 3 reef points. You'll have to try to judge that or get an opinion from a sailmaker.
I can tell you that the reef points on our old 2-reef mainsail and our new 3-reef mainsail are in completely different locations. That is one of the advantages of going with a 3-reef sail -- more "gears" to choose from.
