Can you share your keychain with another Apple ID (my wife)?

We used the same Apple ID for over 10 years. With the addition of Apple Watch, we needed to break apart. When we did, I copied our apple ID keychain over onto her Mac, created a new Apple ID for her and also set up family sharing. So far so good.

Now, we'd like to share one Keychain Access if possible. Is it?

Thanks,
