This is a terrible idea, and I'm far from convinced it will improve clarity.

The solution is to hire people who can be understood, and empower them with the authority to be effective. Elaborate and misleading schemes to mask the problem are disrespectful and insulting to your customers. If the job involves speaking with customers, candidates for it should have the communication skills required. I've dealt on a regular basis with foreigners / ESL'ers who are perfectly capable of speaking English, French, etc. even with an accent.

If the job involved regular heavy lifting, would you hire someone incapable of doing so?
