Sorry, that won't cut the mustard here. That works for hasbro/takara, yes, but not a fan made kit.
People who buy those kits know what they're buying and what it should look like, and won't have consumer mentality towards the original company. It's not a general on the shelf item like "offical" stuff is.

So no, it won't impact their future kits at all due to lack of consumer confidence.
But what they do know now is to produce more of the kits in the future, as I see the only reason this ko exists is due to demand outstripping supply. The thing that may make people not like the original company is the fact they made the run too limited.
And no, I don't condone the ko, and would encourage the original company to go legal on the ko, but really, the ko looks so shite that there's no mistake in what it is, (as I said before, the type of people that buy these things would notice the shocking quality immediately, unless you're an american who laps up ko's), and wouldn't want to buy the ko, nor think it's original.
