I know that rewriting the GINA is way more than a minor issue. 8)
Several groups I've worked with have tried, and even used for a time,
custom GINAs. But they just are too much hassle to maintiain over time.

I certainly would recommend against writing your own. I find it really
hard to buy that writing your own to satisfy the limitations of another
piece of software is going to be anything but a nightmare in the long term.

You're better off calling into some low-level APIs like the NPAPI during
login and password change rather than rewriting the GINA.
