In the first place, no: I am not exactly sure why.
I had other (and soberer) music which I needed to write, and instead I dedicated the laborious portion of a (mostly relaxing) Sunday afternoon (ye gods, such profanation on the Sabbath Day!) to this rather absurd item. I do not believe I had ever before considered a stylish re-scoring of the Pachelbel Canon, and why this particular thought careened through my brain at this particular time baffles me.
It must have been the money.
The parameters were simple: (a) I wanted my own ear to be engaged and amused by the unfolding textures; (b) I limited myself to those instruments which sound reasonably good "out of the box" in the Sibelius sound library; and (c) since this was purely a matter of generating a sound-file, and not any practical matter of assembling actual musicians, I just chose sounds as they occurred to and pleased me, not worrying about logistics of transporting instruments or hiring players.
If it takes on, though, an actual score could be produced . . . .
