However as stated in my previous response, decisions are not taken in a vacuum, when they have repercussions in other affairs of the Church.
The College of Cardinals main task is to appoint a new Pope and the new Pope is selected from the College of Cardinal.
If a new type of Cardinal is needed allowing for lay members (including women) then a reform of the way Popes are elected is required.
While possible I won’t hold my breath over this. Pie in the sky scenarios is a waste of time in my mind, time which could be better spent figuring out how to better transmit Jesus message and how to become better Catholics, something that our current Pope is worried about.

It may be that somewhere in Canon law it states that popes have to be elected from the college of Cardinals, but I am not aware of one (anyone out there?). It is far more likely that the pope is elected from among them simply because they are a subset of a subset; that is, they are (with two exceptions of recent times) all bishops. The net result of that is that they are likely to know one another, or to put it another way, each one is likely to know a significant number of the rest of them, better than they would other bishops, let alone other priests, and to take it a step further, let alone other non-ordained males.
The short of it is that there has to be a significant number of Cardinals who know the individual they will elect well enough that he will garner sufficient votes to be named pope.
If, say, a significant minority of Cardinals were very familiar with a non-Cardinal bishop (let’s take Di Noia, since he has had various posts in Rome since 2002 and was ordained bishop in 2009), it would seem very possible he could be elected. But if, for example, 5 Cardinals in the US were very familiar with, say, a bishop in Canada and would promote him, it would be far more difficult simply because so few other Cardinals would have had any contact at all with the bishop.
Given that we have finally broken through two “issues” - first, a non-Italian Pope, and now, a non-European Pope, it may be possible that we will see someone elected who is not a Cardinal. Old traditions die hard, but this is one that seems possibly to no longer hold so much sway.
Which is not to say that I have anything against an Italian Pope.
