Short answer? No.
If you genuinely think that X-Wing is in a GW-esque state of catastrophic imbalance just because a few lists are more commonly seen than a few other lists, and that a '2.0' or 'banlist' will fix everything, you are demonstrably incorrect by simple observation of GW's current crop of 'games'.
Setting up a '+1 point list', banlist, or whatever else you call it, will only shift the meta around the same way a new release does, and allow a different set of lists to rise to the top and start getting their own set of nerf threads. It's nigh impossible to see all the possible ramifications of changing or removing any given card from the game, and we already have enough danger from that kind of thing with each new one that gets added. That's not even to mention how much more of a barrier this creates for players, who perhaps don't want to have to keep up with a 'banlist' or would prefer if the cards they bought had consistent points costs from one day to the next.
Also, who decides which cards go on this list? FFG? Then you can guarantee the forums will be overrun by topics asking for this or that card to be added/removed from the 'whateverlist' and spitting hate at FFG for putting/not putting certain cards on there. Anyone else? No one can claim 100% lack of bias and so the list will be warped by personal experiences. Just look at this thread alone for how much disagreement as to which cards belong and which don't.
Right now, X-Wing is in a decent (if imperfect) place, where each faction has multiple available build options and no one list dominates all others, and realistically that is the best we can hope for at any given time given the nature of game design. Certainly there are factors/ships that could use addressing, but FFG have demonstrated time and again that they are aware of issues like that and put a lot of effort into making improvements without breaking the game in half (which, as we've seen, one wrong move can do).
Consider also the absolute bottom line here: FFG makes no money from a 'whateverlist', yet it is something that will require a phenomenal amount of effort to successfully maintain and update in line with the meta. Putting 'fixes' in new products might come across a bit devious, but quite honestly it doesn't even come close to the GW 'deliberately break the game to make people buy a thing' school of thought, and all the while FFG are doing as good a job on keeping the game in a healthy state I'm happy to buy a new thing I like to also fix an old thing.
So...no, I think whatever kind of list you're talking about is not a good idea for X-Wing, as all it will create is more problems for the game, more arguments, more work for FFG for no real gain and a less accepting atmosphere for the community (just look at MtG for examples of that).
P.S. For what it is worth, I havnt agreed with a single card on anyone's 'example' lists thus far.
