Cutting some niches from a list
 

I'm building a free porn website which will have several niche categories.
I need to cut some of these niches for later to reduce the initial work (each category is a lot of work):

These are already selected:
Ass / bubble butt
Lesbian
MILF
Teen
Big Tits

These I'd pick in addition, but I should maybe replace some of these to have more popular niches:
Asian
Pornstars
Ebony / Black girls

Maybe later or switch some places with the above list of 3:

Anal
Babes, softcore
Blowjob
Group sex, Orgy
Hard Hardcore
Reality
Toys
Latina

So, from a business point of view, would you pick any from the 3rd list to be replaced with one from the 2nd list and if so, which one(s) and why?

Thank you.
