I don't think you can't, but agree with dave that there will be complications.
as you noted... 'what material', dimensions, hardness, etc.
remember, your nose is at stake, not mine.
What triple trees are you using, maybe someone has one that they can measure and you might be able to use the axle?
Or what length axle do you need?
I have GR/GS front ends that I can measure.
