I guess you could. At the risk of being blunt. Just because you can doesn't always mean you should. It might be fantastic or maybe those walnuts could be used in something else. Are they black walnuts? Around here we gather them up and sell them. Last year we got $16.50 Per hundred weight hulled. (Over the years I've see prices as low at $4.00/100weight in the 70s and in recent years as high as $22.00/100weight The buyers provide the hulling machine you just bring the walnuts. Of course here in NW Arkansas we have a lot of walnut trees.
I hope you have figured out an efficient way to hull, crack and pick out the meat. That's tough work. And they are easy compared to Hickory Nuts. THOSE are some sweet and rich nuts, once you get to the edible parts.
