Oh, just 44 girls? I'm sure that makes a big difference. ;-)

This seems like a really huge amount of work. But i still think you should take your time with some of the girls, there is no need to rush this story. With so many girls you can try many different things. Some might die really fast, but you can absolutely drag it out with some girls and keep them alive for a while, there is a middle ground between Kill them all and the CDL story.
