I think you can, as long as you don't constantly switch back and forth between the two. You could probably still interlock though. If the hair is shorter than an inch in those areas, I see your concern.
You could use a plastic yarn needle to retighten those short areas. I have several locks that keep coming out or are super short that I use mine on.
You just have to cut the length of the needle and then use a nail file to file the top down so it's rounded and smooth. Then widen the hole so your locks fit through the eye.
I use a flathead screwdriver or a pair of scissors to do that. But you have to be gentle and go slow or it will break. Ask me how I know.
I'm not sure if I posted a pic of my needles, but I'll go ahead and do it now so you can see the different sizes I use.
Hope that helps!
The blue needle is regular size out of the package. I didn't cut it. I always use one that I don't alter. That one I use mostly for the long locks and the locks that are not fat on the ends.
