Nope.

The 'shc' generated executable will first decrypt/validate itself and
then launch behind the scenes whatever shell was specified as
its option (or the default shell), feeding it with the original
shell script. The kernel will still not honour the setuid bit.

'shc' was written as a way to obfuscate/ensure the integrity of
released shell scripts, it doesn't parse/understand the script
commands itself, thus it's useless in the OP's scenario.
