Stretching a softail stock frame

[Breakology]

I have a '93 FXSTC that I am looking into having stretched, looking the possibility of having it stretched under the seat with possible swing arm extension so the seat can be moved back a few inches to give me more room between my rear and the pegs. I am a tall guy so this would be a huge improvement in ride comfort.
Just trying to see if anyone has any experience in this area, or has any ideas that could make it work.
I already have 3" forward control extensions, along with drag bars and six inch risers. Not much more I can do to get more room that does not involve getting a new frame or chopping the existing one.

How tall are you? I'm 6'3" and built my own 5" forward controls using the Ness 3" and Cycle Vision 2" kits. Gives you nice leg extension and spaces the controls out away from the bike a little more than an inch if not an inch and a half. Very comfortable and a more practical approach to stretching the frame, if that's what you meant.

I am a little over 6'9". I already have the 3" forward controls, and I have the Kuryakyn wing pegs on order, gonna try those out and see if makes a difference. I can keep moving the controls out as much as possible, but ultimately I would like to have the bike customized a little more to fit my size.
