Interesting idea. One supplier's technical manual fo plastic pipe can be found at:

So far, all of the sizes for 24" nominal pipe seem just a bit off what we need. From experience, these pipes can usually be worked with tools that would work for woodworking. (although some construction gangs use abrasive cutoff wheels intended for pavement cutting - this stinks, basically melts/burns the plastic)
