Here is a proposal for a "Super DLC". The main proposal is for a new hunting dog: Dachshund or Beagle for flushing birds and small game like rabbits, hares, and raccoons.
The DLC will also have a new “mini-map” set on a region of Silver Ridge Peaks, occupying an area about the size of the Layton Lakes Trophy Cabin (or slightly larger), but nowhere near a full-sized reserve. The main attraction will be a large barn and surrounding corrals where players and their dogs can hone their skills shooting all sorts of small game, from rats, squirrels, and woodchucks to pigeons, crows, magpies, wood doves, rabbits, and prairie dogs (with a burrowing mechanic similar to the European rabbits).
To add more variety, it would also include a clay pigeon (skeet) thrower for shotgun practice, as well as a mini-target range with bottles, metal plates, and other items for handguns.
To fully immerse themselves in the experience, players would also get a new costume: a tartan shirt, jeans, cowboy hat, gloves, and cowboy boots.
And of course, new weapons will be included in the DLC (brands and specific models for inspiration only):
Savage 93R17 BTVSS 17 HMR Bolt Action Rifle
Mossberg SA-410 Turkey .410 Semi-Auto Shotgun
Beeman AR2079A air rifle in .22
Anglo Arms 80lb Self-cocking Hand Crossbow (i.e., what is in Classic now).
Essentially the DLC is really for the dog, costume, and weapons, but with some added fun.
