Even for the pros here, I think we are like hitters or golfers - yeah we've done it in the past, but are we in for a slump?
As to the ams here, I would say on half the projects I do, someone connected with it brings me their routing. Only a few have been any good at all, and then only marginally, ignoring lots of basics (don't put greens in deep valleys where they get no sun, will flood, etc., or holes blind over the tops of hills, too close together, too sharp a dogleg, etc.
You don't know what you don't know. And, in your zeal to do something different, you would probably do something really bad that someone else tried and rebuilt later!
Most mention routing, but as Tom D says, feature design aint really easy either. Even if you know you want a Redan, or even just a bunker on the right side of the green, getting the depth, visual scale, etc. right takes a lot of artistic talent and experience.
Basically, most of you think of gca only on a conceptual level, as TEPaul says, but have no ability to translate those concepts to reality. If you add in the time factor (like the owner, or even you as gca would want this thing built in your lifetime!) then you really have little chance.
Short answer:
Me: yes
You: no.*
