 Back crossing F1 autoXphoto plants

Okay, does this make sense in regards to crossing back to the original auto seed stock?
A= dominate auto traits P/photosensitive
+/-a small %
AxP=100%P with 50% recessive a
AxPa=75%A with 25% recessive p
at this point 75% +/- will be auto-flowers, i could from that point continue to cross back to the original A or selectively breed Ap X Ap for another 3 gens(at least 95% auto) to keep more of the original P in there.

Back the tape up. I need it again!
Let it roll! Just as high as the fucker can go!

Should work on paper but after crossing back to the original A you'll loose what you were hoping to gain from the P. I'd go Ap X Ap till you found what you wanted and I mean exactly what you wanted taste, high, yadda yadda then make feminized seed stock from the plant picked. 
That will get you closest to getting all the traits you want in seed form the fastest and get rid of those males at the same time.

cool. My ultimate goal Is to acquire the original auto seeds in regular form (only sold fem)
Any genes from the original P would only be a bonus.
I don't want to cross an auto to the new auto as to not dilute its "super auto" gene pool.
 <--- Super cali haze auto.
i am going to use a female super cali haze(auto) X male Sdog
then use a male from those F1's to back cross to Super Cali haze.
then i will start to stabilize.
the known genetics that will be in this cross are
Blueberry
Chemdawg #4
Colombia
KC 606
Nevilles Haze
Norther lights#5
OG Kush}
Pakistan Kush
Sour Diesel
Thailand Lemon Thai
Unknown Ruderalis
Unknown Sativa Dom Afghan
M.I.R.A.G.E.S
My.Indica.Ruderalis.Afghanica.Genetic.Equillibruim.Sativa induced
i want these seed more this summer then i do buds.Hopefully buy June ill be on the way to make the F2's one more question the f1's from the first cross. They re all photosensitive(+/-) a small percent. will the potency/ flower time be reduced? or would that not show till F2
