Would it be legitimate for someone to claim interest on a tax claimed using form 843?
No. The IRS is often required by law to pay interest on refunded amounts. For example, if a tax refund is paid after the April 15 deadline and more than 45 days after the return is filed, the IRS pays interest. If interest is owed by law in your situation, the IRS will pay it automatically. If interest is not required by law in your situation, they will never pay no matter how eloquent you are. Just claim the amount of tax or penalty that you want returned.
