If you want a save with all the Pokémon already redeemed, well we don't have such a save, but you can use PKHeX to inject them.
If you want a save with all the events as Mystery Gift (before redemption), not possible, as there are not enough redemption slots.
In case no one else replies to you, you can get USUM saves here, here, and here.
What you requested, is something you can do for yourself. :3
