I don't mean to swipe at you, Sabrblade, but one of the fandom things I'm weariest of is the conflation of "I prefer this" with "this is what it SHOULD be". I mean I get what is meant, but it's right up there with "fans deserve ___" as immediately coloring anything that follows.
I don't disagree that the new deco leaves something to be desired. I doubt such a faithful recreation is feasible, and honestly Takara-ish "let's just paint the deo over incongruous sculpted bits" is not exactly an improvement for my tastes. But I'd be fine not touching the clear pink bits on the shoulders, and just adding gray in key spots (the rectangular panels surrounding the shoulder rockets, and the interior of the shoulder panels, leaving a black border in both cases. Maybe pick out some of the sides of the lower torso (move the paint from the grill to some or all of the greebling on the sides).
I don't know how much paint is even available, but based on my utter lack of production knowledge those seem like reasonable minimum spots to make those tweaks. The rest (chest windows, some paneling on the pelvis/thighs) are flat surfaces that can be reprolabeled (yeah, yeah, "I shouldn't have to spend extra" myah myah). At least break up the large single-color expanses and dispel the impression that this guy is wearing a black shirt.
