2 GC parallel process in family: NIW based I-485 and PERM based I-485

[buleon]

Hi,

My family has 2 GC processes ongoing:
1. My wife has pending AOS (I-485) NIW based with approved I-140 and got notification that case moved to local USCIS office (probably for interview).
2. Independently, I got recently approved PERM and my employer to submit I-140 and AOS (I-485). The I-140 premium option will make approved in few weeks.

The question is if we can interfile both I-485, what will create shortcut for my AOS waiting time and finally make us both applicants (principle).
Not sure if it worth it...

Please advise that are the available options for us.

Thanks,
