2 x ninth level slots isn't unbalancing, just do it the honest way. Get to 20th level and earn another 30k xp for your first Epic boon. Done.
I think a different issue is, if it's possible, why isn't everyone doing it? It doesn't seem likely that the PCs are the first people to see whatever exploit they're looking to use, if it's real. If you allow one PC to use Wish for a second 9th-level slot, then it seems to me as though there should logically be other wizards who have wished for that, and maybe a third, or a fourth, etc.

In 3.5 you could explicitly Wish for a Feat, and there were two Feats that might apply.In older D&D , beyond the power of the spell otherwise every wizard would do it.
In 5E I think I'd allow it with the usual 1-3 chance of losing the ability to cast Wish.
I haven't looked at 3.5 in some time but that doesn't sound right to me.In 3.5 you could explicitly Wish for a Feat, and there were two Feats that might apply.
One gave you a new spell (for Sorcerers and Bards mostly), and the other gave you an extra spell slot.
That was the only way to gain Epic spell slots, since you didn't gain them from level advancement.
So in that particular edition, it wasn't simply allowed, it was more or less mainstream when it came to Epic level characters.

I don't recall wish explicitly allowing feats to be gained.
Moreover, I'm basically certain that it wasn't required to gain epic spell slots. As you gained levels beyond 20 you gained epic feats. Which you could use to gain epic spell slots. The way to gain epic spell slots was to gain epic levels.

What would be your ruling if a Wizard wished to have an additional 9th level slot?
