I assume this project is just a hypothetical? Or is there a real world project that you're planning?
Here's where you may have lost my business...
Which the terrain and obstacles will be designed to fit ball golf, since that's what pays the bills. To me, putting a disc golf course on a ball golf course is a resignation that you don't have the land for a dedicated disc golf course, not a benefit. Not that you can't put a decent disc golf course on a ball golf terrain by ignoring the ball golf course layout entirely, but doing so kind of interferes with the ball golf.
Also, of no benefit to me. I'd personally like to get my round done in under two hours. A lot of people are quitting or cutting back on ball golf rounds precisely because they take too long.
This need to make par 70+ disc golf courses seems to stem from some inferiority complex some of us have to make ourselves more like our so-called "big brother sport" in every aspect. In all honesty, we really need to cut that out and run as far from that direction as possible. There's a lot of good middle ground between that and our numerous existing Par 54/SSA 48 layouts we can shoot for.
I also eschew the idea that the people who are most willing to spend money playing a disc golf course want the most challenging layout that can be made. The ball golf industry spent millions over the last 20 years finding out that wasn't necessarily true.
