Common Chimp, Bonobo, Human Hybrids

Sixteen years later, and after a discussion on another thread that risked becoming a hijack I found this the ideal thread to ask: have bonobos and chimps been crossed on purpose, perhaps even under controlled conditions? Are the hybrids viable and fertile? And have they been mixed after birth in the wild or in captivity, meaning has a bonobo baby been raised by a chimpanzee community or a chimp baby been raised by a bonobo community? If so: how did that turn out? Can chimps learn to be “peaceful” and bonobos be culturally taught to be “agressive”? Or is the genetic component too strong?
I know that the words peaceful and aggresive are crude simplifications, but I hope the gist of the question is clear.
