I really wish they kept the blazer, it was probibly one of the best trucks ever made, especially for off roading. If they made a diesel version of the Tahoe with a removable back and roof like the old blazers that would be pretty close, but there isn't anything out there like the Blazer anymore.
The Ford Bronco concept looked promising, but a 4-cyl turbo diesel doesn't. Atleast make it a 6.
