No, it isn't a solution in my opinion, torrents need to be seeded, (at least) initially by Archive.Today, seeding a shit load of multi terabyte torrents is a lot of bandwidth which will probably up costs
Torrents die, and I would especially expect massive torrents like that to die out fast, there's not a lot of people who can spare that much storage and/or bandwidth, it's not just "go buy a few drives, put in and seed", especially not for that duration of time.
