Yes, but Ruby DO SEEMS to require the development on the new engine due to the particular quality and style of the voicebank itself, while Luka don't represents (technologically) a thing for the V4 software; V3 already covers all the needs for Megurine Luka's extensions.

Unless Luka show a more "special" quality beyond the power/whisper/clear vocals that V3 engine ALREADY allows properly, I don't see why to move her to V4.
