I could definitely get on board with some very difficult Light Party dungeon crawls (Much more difficult than original Pharos) that drop i95 or i100 armor. Make them take a legitimate 90 minutes to complete and add some rather high risk of failure if you let it drop i100 gear. No until you finish the dungeon, then you would get:

- 100% chance of 1 i100 accessory
- 100% chance of 1 i100 armor piece
- 50% chance of 1 level IV materia
- 20% chance of one Oil of Time
- 20% chance of one Sand of Time
- 5% chance on of one Unidentified Allagan Tomestone

No Myth or Sol.
