TL; DR version:
Having more than one good basket placement requires designing a course with that in mind. To have multiple pins that are good requires more than simply moving the basket around to different spots within the circle.
Longer, clearer version for people who care about reasoning and good discussion:
I've been thinking about your ideas more. I really like drawing inspiration from ball golf for DG design, but when it comes to "putting areas," I see very little reason to glean from golf. Where you are on a golf green matters a lot based on inches of elevation in the green. Elevation on a disc golf green only matters when it is multiple feet of change, and sometimes not even then. When I say "matters" I mean it both influences your putt and changes the likelihood of you making it.
Additionally, I've never seen a tree in the way on a golf green. There are sand bunkers close to some holes, but if you're in a bunker, you're not putting. DG's putting obstacles (in addition to elevation) are mainly trees and what's on the other side of the basket (OB close behind). All that to say, DG's putting area is drastically different than golf.
I think a better way to move pins is to either have totally different putting areas, or to have basket placements far enough apart in the same putting area where it makes the approach and puts different. Maybe the putting area has a 50' wide mound with a lone bushy tree (cedar or similar) directly in the center. One day you place the pin on the right of the tree, and the next day on the left. Assuming a multi-shot hole and a restricted fairway, that changes the ideal approach shot (whatever that is varies from person to person). If someone's ideal approach shot one day is from the left side of the fairway, perhaps moving the pin will make their ideal approach shot now be from the right side of the fairway. If so, that changes the previous shot as well.
I think that having good, multiple pins should (in most cases) should affect a hole throughout. Also, most of what I've said about having multiple pins should (ideally) apply to multiple tees as well.
