I would just look for a used hardtail; you can find them for around $500. You can use it on the xc trails you've been riding, and when you ride the more demanding trails: take out the enduro.

It would be hard to move the enduro away from its mini dh traits to a more xc type of ride. As others have stated, you can get an adjustable fork and lighter components, but that already puts you well over a thousand dollars. If you need a more xc type of bike, get the hardtail, they are very fun to ride the trails they are intended for. Then keep the enduro the way it is so you don't lose the aggressiveness of the bike for the trails it was designed for.
