8 weeks into flowering and bad timing

[Indaking]

I have a mystery strain that is 8 weeks into flowering and is doing poorly. My great Dane topped it early summer and I've nursed it back to a plant. Flowering on 12/12 for 8 weeks. (Religiously) But I started a few autos and a chronic photo a week ago and they are in the same grow room. My thoughts are to bring the flowering plant to a window for a while longer and flipping the new seedlings to 18/6 in the grow room. But doing that, the flowering plant will only get 9 hrs of day light. As well, there may possibly be light leakage so the light/dark times won't be regimental.
Will it start to re-veg? Will this screw it up more than it already is? The trics are still white right now.
Any advice would be appreciated.
Thanks

If you switch from 12/12 to 18/6, and the plant is flowering, it will revert back to the veg state but will take time to recover.

Also, if you're in week 8 of flower, reveg is possible but you're going to seriously confuse your plant. Reveg will take a long time. It may not be worth it....

Thanks Pontiacman
Any idea what will happen if there's 9 hrs or less of light for the flowering plant?

It will just keep flowering. It's all in the light cycle....
