Thomas Metzinger addresses this exact question in his book _The Ego Tunnel_ ([1] a great non-technical overview of his work in Philosophy-o-Mind/Neuroscience), and he comes down strongly on the side that any artificial generation of "consciousness" would be reckless and could likely increasing the amount of suffering in the world.
Happy to share. Metzinger takes a hard line on strong materialism and against the existence of the self. For a more general overview of current strains of scientific thoughts on consciousness I'd recommend _Conversations on Consciousness_ [1] which interviews leading researchers who are representative of the varied approaches to the field.
