Although technically speaking, the concept is not that otherworldly. There was a Soviet design in the late 70s/early 80s, called Object 490B, named "Belka". It never went beyond paper drawings.
Depends on the intended role really. Wheeled APCs like Stryker MGS or Centauro are mostly for infantry support. Anti armor role emphasis will require light tanks like Sprut-SD or CV 90-120, with tracked chassis.
