I suggest talking with an experienced machinist.
Having the right materials and the machines to work it goes a long way.
On my initial ride I thought "how awful" of the foot peg's location but I quickly got used to them and I am OK with them now.
The one thing I did though, was replacing them with pegs that have a soft rubber top. Found 2 on eBay:

A bit of work but I enjoy doing these kinds of mods to fix something that bothers me.
They provide a better grip for the shoes and even absorb some vibration.
If anyone is interested I'd be glad to post some pics but I am sure most people think I am nuts doing something like this.
To me, the big deal was the handlebar: could not get used to being so low and I ended up replacing it with one a lot higher.
A heck of a lot more comfortable now, being able to sit up straight (my back thanks me on every ride).
Another thing I could not stand was the kickstand being so short so I made a "bootie" nearly 1 inch in height. Now, the bike's inclination when on a level surface is just right.
I have a small lathe and milling machine and was able to make these things myself.
A good machinist would have no trouble making some sort of extension or base to lower the pegs and/or move them forward by certain amount.
It might not be cheap but then again neither are the SR/Fs
