The only way to "take over" a spider leg, meaning to have it score on your own alliance, would be to place your own ringer over a spoiler, which would mean placing a spoiler over the opposing alliance's ringer, then pop one of yours and put that over the spoiler.

I'm sure if a tube is popped, and this event happened as said above, the refs would not count the popped ringer over a spoiler and the call will stand as that whole spider leg negated for points on either alliance.
