Does it really seem hostile? Everyone seem very firm on their positions, but I don't think it's been hostile.
But if that were the case, why would they slap together a valk that can't transform. If they we're in such a rush to get back to battle, wouldn't it take more time to switch the nosecones back than to just give someone the "keys" to a fully working valk that they painted blue? And who's to say that they even intended on painting it back? I say they painted a 1D for the couple as a wedding gift. If they don't run low on Valks in battle, it could just stay out of combat. And if it did see battle again, who ever had to fly it probably "bought the farm" in a nice blue VF-1D
Why would they paint the whole valk? Weren't you the one who said that it never saw other modes and was only used for 10 minutes before they had to paint it back. If that hypothesis holds true, they would've just painted it in fighter mode.
They're painting a combat jet, not a show car. I don't think they'd spend too much time or effort slapping a paintjob on a Valk that was going to get shot at the next day. Besides, it's usually moving too quick for anyone to care if it wasn't painted perfectly.
