Even if all the BTC in stuck transactions were stolen (which is impossible, because most of the inputs were spent in three to six stuck transactions), it is still only a tenth of what MtGox has made in fees over the years. It is certainly not going to bankrupt them. You have to make up something more credible than that if you want to make people believe in your scam.
By the way: I really thanks for your comments here. There is so much scaremongering and desire for the escalation in these parts. So, is really enjoyable to read your posts.
