Victoria Rules
I ran "Keep on the Shadowfell" like this after converting it to 1e and given its design shortcomings it certainly did well enough.Likewise, an old school dm can run, say, Pyramid of Shadows in an old-skool way. It's hard to avoid how linear the map is, but you can spice it up by having new threats arrive behind the pcs, by letting one encounter reinforce another, and by accepting the possibility that the pcs will be trapped inside forever instead of automatically giving them an escape route.
