I figured a MP+ Wheeljack with a simplified, screen-accurate colour scheme would be a thing as soon as MP14+ was announced. I'm surprised it hasn't been announced yet.
Megatron's colour scheme is already pretty screen-accurate, and the figure even uses the cartoon version of the Decepticon emblem with three central spikes instead of the traditional version with two central spikes. A MP+ version doesn't seem necessary.
MP-11's colour scheme is pretty screen-accurate. I don't see how you could improve the colour scheme and make it 'more screen-accurate'. TakaraTOMY could paint the figure grey instead of having unpainted plastic, but that wouldn't really improve the colour.
