I believe that someone else on the board here tried this and found it to work well. You may have more control, but remember, you still won't have any more room under the throat of your machine than you would the other way. The other person who did this felt it was helpful. I have a Flynn frame that I have never used, and you are correct, that is the way you sew when using that...from the end of the machine, with the machine oriented as a longarm machine would be. Good luck, would be interested in finding out how you like it.
And the pool noodle roll up would be like the rails of a longarm. That's an interesting idea too.
