Not all sites will allow for such variation in angle. Part of the fun in golf is variety and the ever-changing playing field. There are numerous influences to golf holes — daily set-up, wind, turf condition (wet, dry, etc.), pin position, rough condition, seasonal growth (tree canopies, leaves, etc.), hazard condition...and the list goes on.
Options and set-up variation at the tees is a viable approach if it fits. Personally and professionally, an "architect who can't make up their mind" probably yields a decent course overall. It is those who have made up their minds and follow a single path of style and design philosophy which yield boring layoyts.
