In WC3 there were seats, at least for the cats- I remember that I loved to shoot them down once the navpoint was clear
In WC4 it was a complete cockpit part around the pilot, not sure about WCP, but I think there was also something like that.
As for our game, it would be quite difficult to make. Let's say we forget all other ships and just think about the player, we would need some sort of model which we can switch too. But it would suck, if you can't see your own ship stalling and exploding in the end. So the only way of doing this is some sort of ingame cutscene which will be shown, there we could fake it in clever timing, BUT then it must be scripted in each mission, and will be another problem in missions where you could choose your fighter because the script needs to know which fighter the player has used.
Therefore the necessary work compared with the need is rather unbalanced, so I think it's quite unlikely
However, I think we could add at least a model for an ejected pilot if someone wants to make a SAR mission
