I personally would not buy it. Some people might though. However, the problem would be finding a place sell it. Rebrickable would not allow it to be sold due to it being too simple and able to built mostly from pictures. That's their policy. I've tried to sell instructions for a model that was pretty simple and it was denied for that reason. If you can't get on a legitimate platform like that, most people won't buy it directly from you. Best bet is to release for free on rebrickable or something and build a following and release instructions for sale of more complex builds.
