Please, please, PLEASE!, I'd really like to have a bike path from the North 40 to the Forums Plaza.
You can't get a seat on the northbound tram to the N40 in the afternoon, unless you start at its origin AND are willing to displace some cane-wielding octogenarian or mother carrying small children who missed their nap. Also, the trams stop before the evening events finish at Theater in the Woods. It's a long, miserable walk from Theater in the Woods to the N40 after walking around the show all day.
The bike path from the N40 to the main gate doesn't help much, because it's a longer ride plus a long walk plus two trams to the Forums Plaza.
