Just to clarify, is this request strictly about page numbering and 
margins (something I believe LilyPond already supports albeit via 
manual* configuration), or does it also encompass the automatic 
synchronization between the primo and secondo parts at each page break 
(also something that requires manual** intervention to achieve at the 
moment)?

* Each part's margins can be customized uniquely to achieve the desired 
mirroring, and the page numbering needs only a little arithmetic to show 
up as odd-only or even-only.

** Providing things do not align by chance, adding explicit \pageBreak 
commands would ensure that page turns happen at the same moment.
