He should throw in a piece of Lufa's Aspect of Rationality. Ves would remain an innovative Passionate Designer at his core, but at the flip of a switch he could temporarily become Rational and copy other specialties.
I worry that would backfire. Ketis and Sharpie are both working towards swords, one as a mech designer and one as a user. moving forward as a double helix. An Emotional mech designer and a Rational are both mech designers, but vastly opposed to each other. Might give Ves split personality or mess with the Life flavor of his spiritual energy.

However, I am not sure it's wise to bank on the tainted High serum from the Supreme Sage. With the CFA you at least counted on some track record across time. Now Ves wants to overboost his companion with unreliable material?
