I get where your coming from. You will always need a lathe to turn down the inside to make them fit ... Unless ...

1 1/2 inch pvc you can use whatever tape and 1 1/4peg you like.
tape the peg lightly and evenly so the pvc slides over the taped peg without binding up. .
Most likely with all the race forks it will never work unless you grind the hell out of the front peg.
It creates a natural cushion too.
Enjoy
