Ok i'll give this one a shot even though my hair texture has somewhat changed, but i'm still a wurly depending on the humidity. I did a blunt cut trim back when I was at shoulder length.
For some reason it looked nice for a couple of months until I reached BSL where I started getting tapering as my hair gets longer, my texture as you can see in my current pictures is much different now and a lot thinner as my hair gets longer. I plan to just wait until I reach my goal of classic length where I will be able to maintain a blunt cut. It is possible for us wurly/curly peeps to get a blunt cut, but since our hair is not straight be aware that it can change as your hair gets longer or until you reach your goal where you can get regular blunt trims to maintain. What is your goal length? Maybe that will shed some light for me.
ETA: Ok I've re-read your profile and it says your goal is hip length. If that is the case, then I'd wait until a lot of your hair reaches hip length (just make sure you do the occasional S&D along the way), maybe an inch or two past hip and then get a blunt cut. Also if you like to wear buns then a blunt cut can be more challenging then if you had a "v" or "moon shape" hemline. I know with my U- hemline making buns is less problematic now then when I had a blunt cut cause I'd have to pin down hairs that stick out when I tuck it in. However, if you like to wear your hair down most of the time, then go for it, just remember that it will take a lot slower for you to reach your goal length of hip if you have to keep making blunt trims the moment it looses its form. It really depends how fast you want to reach your goal. If you want to take your time then you'll have the luxury to do so, but if you want hip length really fast, then I'd avoid trims and S&D only if you need it. I hope that helps.
