The reorientation of Gyro from Geppetto-like father figure to arrogant and socially awkward genius is a pretty spot-on modernization of his role, reflecting our current expectations of the trope. So, while I don't think he's going to be evil, I do think he's going to remain a jackass.
I honestly dont see anything modernising about it. The only relevant word is murder. There isnt anything left of his original character.
