how to combine generic firmware and Japanese drivers?

Not sure if this is the right place to ask this, if not just move it. TY:)

I have an Xperia Z3 SO-01G from Japan.
I updated it with the latest firmware from xperifirm, however, the lollipop version is only 5.02 and they don't have 5.1.1 from Docomo
When I use the generic firmware NFC doesn't work.

My question is, is it possible to use the generic firmware and just extract the NFC drivers from the docomo firmware?
I want to use the generic firmware with the latest version of lollipop with no issues regarding the drivers.

I will highly appreciate if someone could help.

Thanks a lot
