MD83FO,
I think it's admirable that you're trying to use technology and the enthusiasm of youth to make things easier for you.
BUT, unless it's an SOP for your airline, please don't do it.
Why are you willing to operate outside SOPs, using a procedure which is difficult for other crew to monitor, when there is a perfectly good SOP to operate to? Why put your neck on the line?
If you make an error using your procedure, do you think you'll get any thanks?
Fly the approach properly, accept that the slope is slightly steeper than normal......and go home safely.
