More than that: you'd close-to-have to rewrite the entire game from the ground up. Have fun!I could use 4E to clone AD&D, of course you would rewrite the classes and dump it's powers.
Feats don't fit in 1e, nor do tiers, nor does the 3e-4e skill system (though the skill system could at least be made to work, sort of). Something would have to fill the gap in 4e between commoner and 1st level PC - a gap that 1e largely doesn't have - so you'd need to design several sub-levels. I don't think 1e can handle PCs going to 30th level on a consistent basis. 3e-4e style 'additive' multiclassing won't fit in 1e. And so on.
When 4e came out I actually gave this all a fair amount of thought: I was ready to start a new campaign anyway (which is the best time to overhaul the system!) and looked at whether I could kitbash 4e into something I'd want to run. On getting halfway through the list above I abandoned the idea and stuck with refreshing our existing system.
