While I think its possible, I dont' think it should be the core.
I think its fine to assume that characters are the same level, that they gain xp at the same rate and level at the same rate. Further, new players join at the same level as the group.
Balance is hard enough when teh group is the same level, and since 5e will likely be a little lighter on the balance hammer, I would rather not introduce any unbalancing elements that could easily be avoided.
Now groups that want unbalanced levels are already accepted imbalance by default, so no harm there.
