Hypothetical Auto-flowering situation

I would like to try breeding 2 different strains, however all I have to breed with is: 1 fully developed auto-flowering type mother (which I really like) and a bunch of ak-47 seeds (which I also really like).
This may seem like a dumb question but I've never let my lady's grow into extreme age b4 especially not a auto-flowering type.
What would happen to the fully developed auto-flowering plant if I simply didn't harvest the buds, but instead waited about 6-9 weeks for some ak-47 males to show up and mate with her?
