Before I knew of this thread, I made my own epic boons. This was partly because I thought the boons from the DMG were kinda limited. I know you already made your own boon system, but perhaps you can draw some inspiration from the boons I made.
Boons:

2. Cause More is Better: Gain max hit points every level (reroll if already rolled)
3. High Magic: Gain an extra spell slot. You can have only one 9 th level extra slot, two 8 th level slots,
three 7 th level slots etc. Reroll if you don’t have access to spells.

ability to breath underwater (reroll if you can already swim)

choose (larger: increase your range by 5 feet and gain +4 damage on your melee attacks, shorter:
