I've updated the "old" version with the due changes to the mallets (and several other small things fixed). The link in the initial post is now updated.
I've also tried a version with more MIRacle, and a reduced mix/tail of MIR. I've probably not done a great job, since I find it not very realistic, and without that "gloss", making the sound seem to be immersed in the space, that I find in the MIR/less MIRacle version.
Holst - Mercury (VI) (with less MIR and more MIRacle)
I must be the biggest fan of pure MIR!

EDIT: Added a version for the Synchron libraries (with Synchronized Woodwinds and VI Harps).
