So, if you can tech that skill to talent-less Lee, why you need Tailed Beasts at all? Anyone who can open a 7th gate can equal a Host, anyone who can open 8th can effortlessly kill a host if needed. Get some prodigies and you won't need unreliable beasties at all.
Opening the 8th Gate kills you. An average Shinobi opening the 8th Gate becomes as strong as a Kage, not as strong as a Bijuu. Sure someone like Gai could probably take on the Nine Tails by opening the 8th Gate, but Gai is special and it would kill him, leaving him about as well of as the 4th in that department.
