There's absolutely zero chance of them rasing the peg any time soon. If it were that viable and straightfporward, they would've done it already - why do you think they didn't do anything about 6 months ago? EUR/CHF was rising up towards 1.25, and it would have seemed like the perfect time to raise the peg...but they didn't (and there's obviously a good reason for it). With more pressure than ever on the Swissie now, an increase in the floor is wishful thinking to say the least.
The peg cannot go on forever, as they're spending billions defending it already. The longer the crisis persists, and money flows into Switzerland, it's possible it could get to stage where the amount of money spent / Francs printed by the SNB will be detrimental to the economy and it will have to be abandoned (like the 1.50 limit was several years back). The crisis in the eurozone is more likely to come to a head than to 'sort itself out'.
