No news yet on this. I'm looking forward to see fellow member Giellea's plan to replace the ZF hands with XF hands. Its a mod that looks promising.
The Xf hands can be adapted to the Zf with a little work, unfortunately an Xf hand broke in the process, so as not to risk any more, we decided to send the hands to the Legend, for the ZF mod. They are works of extreme precision, if you want to replace the hands, send them to Leggenda.
