Good trick question. The answer is no, because there's no such thing as "feminized plants". :)
The seeds are called feminized instead of female seeds because they do not result in 100% female phenos. Those that grow out to be females, are just that, females. Ideally you would stress it in several ways to see if it's not prone to herm, but that goes for both females from regular seeds and females from feminized seeds.
It all depends on the integrity and genetic traits of both P1 strains, and the honesty and integrity of the original breeder of the P1's. Are the P1"s both IBL strains, e.c.t.....Depending on the variables you can run the gamete from a myriad of beautiful F1 pheno's to choose from all the way to the opposite end of the spectrum and everywhere in between, causing much havoc and creating a myriad of problems, don't forget polluting the gene pool even more. KNOW what you are working with and WHAT you are working towards. Obviously in an instance like this error on the side of causing and do much testing before releasing any of the resultant seeds and offspring.
The main thing is to have some fun and experiment but be CAREFUL.
