I think the thing is just how badly do you want the design, I always ask myself is it a want or a need.
Perhaps the digitizer could reduce the design for you, why not ask they can only say No, but then again they may surprise you. Good luck
I would not be surprised if your machine would not let you downsize that much. It is the 6.81 that is the issue. Most machines will change the stitch count as well. Ha ha so my answer really is "I don't know"
Kindly ask the digitizer if they would adjust the size for you. Some are willing to do so.
