On the contrary, it would be a glorious victory for the occupiers and there would be dancing (and structure fires) in the streets.
If you're referring to the occupy movement people, I'd say that in general they would only support this if it was only being done to the "1%", and then only if they were confident that the money would go at least semi-directly to the "99%", instead of being used to prop up banks and such.

Bailout, Austerity, Confiscation: Cyprus Reveals the 3rd Phase of the Great Bank Robbery | Scriptonite Daily
The productive capability of the 99% and the real economy have been subordinated to service the debt of the banking sector of the 1%. But with Cyprus, they have crossed the rubicon: a direct confiscation of personal, private wealth from your bank account to bail out banks...
The global 99% need to watch the developments in Cyprus very closely. The government of Cyprus passing this measure will mean the effective end of private wealth for the 99%. It sets the precedent of governments legislating away a person’s right to their own money, at the direct request of this renegade banking system.
