Space: 1999 is at the top of my list. I'd set it in the year 2199, but I'd keep the Eagle transporters, Moonbase Alpha, props, and even the orange spacesuits unchanged from the original series. Rather than deal with a runaway moon, though, it would be about Earth's first contact with extraterrestrials and the chaos that ensues when the aliens claim that Earth was really theirs millions of years ago and that Humans are a weed that took over while they were away.
I'd also redo SeaQuest, but I'd set it much farther into the future (around 2120). I'd keep a lot of the first season elements, but I'd also keep some second and third season elements like a race of genetically engineered Humans and tensions escalating between newly formed nations.
Knight Rider. I'd keep it simple and deal with a lone crime fighter working for a secret federal agency going up against various bad guys, but I'd feature a kick-butt female lead as Michele Knight and the new KITT would be voiced by LeVar Burton and be something of a smart-ass.
