The expanded universe is full of additional upgraded X-Wing variants developed after the fall of the Empire, but they all supposedly basically followed the same general design.
On the other hand, the Z-95s had far more extensive modifications made to them, or so we are generally led to believe. The various depictions of the Z-95 design have the single engine or the four engines like the most popular depictions of the X-Wing (and in both cases, the basic engine arrangement is supposed to have carried over to the X-Wing, whether the four engine nacelles were separate r split). There was at least one variant that supposedly had four fixed laser cannon too, the Z-95T/Z-95 Headhunter T: http://www.galacticempiredatabank.com/Z-95Headhunter-t.jpg
Whatever the case, the development of the two designs are supposed to have been linked, with the X-Wing following on from the Z-95. If you go ahead and reimagine the X-Wing, it would seem advisable to do so in a way that it cannot look like you're confusing the two or confusing the order of development. I can now see I was wrong to have been in the Z-95 camp, but it still looks like a regression from the original design we saw in the first movies to me. If I'm supposed to believe that anything has changed 30 years on from the events of Episode VI, I would imagine that it would be a heavier, more complex design. Just look at real life examples, like the F-16A and F-16E.
