How would you have wanted Christa to return in-game?

In Season 2, Episode 1, Christa disappears, possibly dying, after the encounter with the scavengers. If Christa had appeared again in-game, I have a few different possibilities as to when and how that might have happened:

1. At the ski lodge, possibly replacing Kenny.

2. In the pen at Howe's, possibly replacing Jane.

3. Making the Michonne DLC into the Christa DLC.

4. Taking Clementine's role in Season 3.

5. Taking Lily's role in Season 4, which, according to Kent Mudle, almost happened.

How would you have done it?
