A rouse would be cool, but since they will instantly know that we are other players, it's an instant give away; no matter how good RPers they are, knowing that we aren't DM NPCs will set them ready for our strike.
The only way that would be viable would be if the DM posted for us, which isn't much fun, I'd think.
Plus we'd need double the numbers to really distract the PCs and still have enough of a force to storm the tower behind them.
The very best outcome I see is that the PCs only have 1 or 2 of there own on watch on the top/airship. With a bit of luck, we should be able to take out at least one before anyone else shows up.
Ideally, we'd want to isolate each PC, but I'm not holding my breath on that.
Also, before we close in, we'll want to see if there are any doors/hatches up top we can seal to at least slow down reinforcements.
