I can't find the exact post, but Donald X., the game's creator, is strongly against taking such equalizing changes. There is luck in the game, undeniably, but that isn't limited to your starting hand. Bottemdecking one of your cards bought before your first shuffle is frustrating as well, which has an even higher likelyhood than a 2/5 opening.
In the end, the luck should even out. Usually it does, but most people are much more prone to remember their bad luck (3/4 when opponent had 2/5 and a Junker at 5 in the Kingdom) that their good luck (the other way around).
