I don't think I can. I've tried changing the face options, but I didn't
find a way to customize it the way I want, with different backgrounds or
font-weight. For example, I can't set the `mode-line-buffer-id` of
`mode-line` face to have bold font and the `mode-line-inactive` to have a
font without bold.

I'm not sure how I can customize the way I want with
`mode-line-buffer-identification` yet, so maybe that's why having another
face to customize the inactive state still makes sense. I also found this
discussion:
https://emacs.stackexchange.com/questions/10033/change-mode-line-buffer-id-face-for-inactive-windows
- but I don't think there's a solution there.
