Yes it is possible. But you need the shell (which handles the redirect)
to run as root.

$ sudo echo package ~x86 >> /etc/portage/package.keywords

will run the redirection as user, where:

$ sudo bash -c "echo package ~x86 >> /etc/portage/package.keywords"

will run the redirection as root.

For stuff like this, I'd recommend you to write simple shell functions:

addkeyword(){
  sudo bash -c "echo $* >> /etc/portage/package.keywords"
}

Write them in your .bashrc and their avaible when you need it.

Use it like this:

$ addkeyword package ~x86
