Oh, I adore Jackie in this! You've captured her perfectly, especially here:

I only got on because I was me. Not Mrs. Peter Tyler me, but Jackie off the Powell Estate me. Works as well here as it ever did back home.

And I'd love to see her actually managing to get 'John' around for dinner. I could see sparks flying both when she sees the resemblance and when he's rude to her, as he would be - which will also remind her of the Doctor.
