Those are nice suggestions dear, but put yourself in the makers of SSB's place. Surely there is unlimited room to make an entirely fresh and individual character moveset, but they know there is a character duo which's moves could as well be the BK duo's moves (mostly). It would save them effort and time, just like it did with Ganondorf. Of course if they think through it and decide that making the BKD partly a moveset clone would negatively affect the sales too strongly, they would end up giving them an entirely individual moveset. If they figure that copying the moveset won't make much of a difference in sales, however, surely they wouldn't just waste their time giving him an individual moveset out of love for their customers if copy and pasting does the job just as well. I strongly believe that the DHD's moves with the duck would perfectly fit to Banjo and Kazooie. If they see it the same way and don't expect many customers to refuse to buy the DLC if it's mostly a moveset clone, then I'm certain they won't hesitate to copy the moveset. See, the problem is that, true DH has a bird on his back, but he also has no use of his hands or his feet, being on all fours and all. If Banjo gets added, he'd need a model, but would it be on all fours like DH? No. The only moves that could actually be duplicated from DH would be like his neautral air, but that's all because it works with his character build.

Making characters isn't as easy as copy paste, Samus' neutral B is similar to Lucario's and Rosalina and Zelda have similar forward smashes, but they couldn't just carry one from the other, because they have different stances and builds. So even though people are going to continue making the DH comparison to Banjo, they wouldn't really end up being the same, and if they did make his jabs and areals exact copies of DH, it wouldn't be easier than making new ones.

tldr; you don't know enough about programming to make a viable argument over whether or not a character could be half-duplicated.
