Is it possible to start Safari 6.0 in 32bit mode ?

I tried the ways i know:

1. Get Info - 32bit Mode - Start ==> runs in 64 bit
2. arch -i386 /Applications/Safari.app/Contents/MacOs/Safari ==> results in error

is it still somehow possible to run Safari in 32bit ? I need it in order to work with ManyCam which can only operate in 32bit.
