nope. Salt is good for eliminating rainbow tables and similar vectors. At this level, let's just say you go after uppercase, lowercase, digits and 20 different symbols, (a total of 82 letters) you'll wind up with 551,368 possible combinations. The only way to make it "safe" would be to get a hash method that would take multiple seconds to run on good hardware. (as a comparison, I crack raw NTLM at something on the order of billions of hashes per second)
