I think the lack of his "cape" is a problem, but not in the way people are thinking of. Blurr has that because he's a near-total shellformer, with his robot mode made almost entirely out of blue parts that aren't part of his silver vehicle mode, and Pointblank is not. You can put Blurr's colors on Pointblank in either mode and have it be immediately recognizable as Armada Blurr, but the Blurr-decoed Pointblank robot doesn't turn into the Blurr-decoed Pointblank car. Even an alternate "backwards" robot mode would still require his big blue boots to turn into the silver rear third of the car.
I do think a "compromise" deco is possible that would be immediately recognizable as Armada Blurr in both modes, but I also think it would be further outside the lines than Hasbro's been willing to color lately, to say nothing of fan reaction.
