Not to seem defensive, and I may be interpereting your comment wrongly; but:
I get why it happens, it's just poor for the end comsumer, that's all.
I never watched IBO in full, but in the end it's a show made to sell merchandise. (doesn't mean it can't be good, I personally disliked it but loved Thunderbolt, The Origin, and Unicorn OVA's) They didn't have to reuse parts. I guess it cut down on their price, but comparing to other HG's that isn't super apparent.
Not my point. My point was, in the case of the Transient, you could spend a bit more for an all around better kit.
