Future cloning.

[Captain_Bravo]

How about, instead of adding a bunch of stuff in, you just promote more interdependence with what's already there? Make cloning only able to clone monkeys. You don't just toss a body in the scanner, press a button, and they're good to go. You clone a monkey body for them, cut out the brain, stick it in the new body, (Insert step here that's basically strange reagent without having to rely on chemistry) and then use the DNA modifier to make them human again.

There, cloning is now a more involved, more hands-on process. It requires greater knowledge of genetics to work effectively, they have to use the operating tables in medbay, or farm out bodies to doctors and roboticists to get the brains removed, and most importantly we'll be able to clone monkeys!
