Hi Steve - my vote would be the ImAg and lead-free assembly choice. All three of your options should work with each having both pluses and minuses. My preference is to solder to copper rather than nickel if given a choice.

[TN] Leaded or non
Hi All,
I have an 18 layer rigid flex (buried and blind) that we are preparing to put the surface finish on and then assemble.
Lots of BGA's etc.
The BGA's are lead free.
Options:
1) ENIG and lead free assembly
2) Immersion silver and lead free assembly
3) HASL and leaded assembly
Hi end military product.
Thoughts or comments would be appreciated.
Thanks. Steve Kelly
