I think you'll find it pretty much comes down to how good of a builder you can be, and how much the axles will hold ; )
You'll find differing opinions of value, and maybe some good advice about doing such, but I'm also guessing the value is what you can get out of it, and how much it's worth to you.
Now, that I haven't really answered any of your questions, i'll let someone else reply. haha
