I would love to see it become re-pegged to a basket of currencies and commodities.

Eg.

10% Dollar
10% Euro
10% Swiss Franc
10% Gold
10% Silver
10% Platinum
10% Oil
10% Corn
10% Lithium
10% Copper

It wouldn't be very difficult technically. The harder part is just getting consensus on doing it and when to start. The starting date would determine the weight of each commodity (ie. find the weight of eg. copper that = $0.10 on that date, and that represents a portion of the peg from then on)
