No actual write-up seems to have ever been completed for the Cheyenne, but TSN did complete two pictures of it.

Hey, I coulda swore I did a writeup for the Cheyenne...

Ah, here we go. Dredged up from 5 years ago... Mind you I think I later scrapped this and left it open for someone else to do.
Cheyenne Class
The Cheyenne class starship development project was started in 2347 after Starfleet requested a replacement of the aging Constellation class, and a class to complement the New Orleans class, which was currently under development. The problem of the Constellation's enormous energy requirements were addressed, and it was decided that the warp nacelles currently being used on the New Orleans class would alleviate this problem in the larger Cheyenne class. After initial testing, it was discovered that the Cheyenne class consumed more energy than the Constellation class. The project was put on hiatus until a power consumption medium could be reached.
To solve the energy consumption problem, a new type of nacelle was developed. It was specially designed for the Cheyenne class, and it tested out perfectly. At impulse speed the ship was maneuverable, and it was as efficient at warp speeds as the New Orleans.
After the testing stages were complete, the U.S.S. Cheyenne was put in active service and production for 20 more hulls was authorized. The Cheyenne class still remains in service today as a long range scout.
Timeline
2347: The Cheyenne class development class is started at Utopia Planitia
2349: Construction is started on the spaceframe
2351: Warp drive and computer cores arrive to be fitted into spaceframe
2351: Speed trials are performed on the spaceframe of the Cheyenne
2352: Hull skin is applied
2354: U.S.S. Cheyenne leaves drydock on impulse power for low power tests on all systems
2355: Nacelle pylon structures are found to be faulty. Cheyenne returns to drydock to be fitted with new pylons
2356: Warp nacelles are found as the cause to poor fuel consumption. A new design of nacelle is fitted
2357: New nacelle is heralded a success. U.S.S. Cheyenne leaves Terran System for shakedown
2359: U.S.S. Cheyenne is commissioned. Work begins on hull no. 51203

Call me wierd, but I always did like the Cheyenne. Kudos on the good drawing.

I like the Cheyenne too, but I don't see it as a replacement for the Constellation. The large shuttlebays on the Constellation suggest to me an entirely different mission profile.

I think the Chyenne would have been designed long after the Constellation's "replacment" (whatever that might be) was in service.
Possibly as a rapid-response design for protecting colonies from raids along the border with the Cardassians, Tholians, Tzenkethi and the Tofu men of the Vegan Empire.

I love conjecture on highlighters on a kitbash. Nice work
