At the bubble of any tournament open/call ranges are pretty much irrelevant in my opinion. This is due to the fact that at this particular stage your main priority should be 'not busting', thus ICM factor greatly prevails chip EV.
Naturally, the first thing that comes to your mind is to tighten up your range, but guess what - everyone will do that. No one wants to be a bubble boy.
So, you should be focusing more on stack sizes at the table, position, and actions before you in the hand.
If you have a commanding chip lead, for example, then you actually should play super aggressively, since you can apply a lot of pressure to your opponents. Because, once again, no one wants to bust at the bubble.
If you have a middle stack at the table, you should still apply pressure on smaller stacks, but at the same time be as tight as possible against players who cover you.
When you have the smallest stack, and cannot put pressure on any of your opponents, your only option is actually to fold everything except premium hands. If you bust with aces or kings, well, so be it, but it doesn't happen too often anyways.
