Filing amended federal tax return just to attach a written document

I would like to electronically file our tax return, but I need to include the "Rental Real Estate Professional Election" document (just three lines of print). 

Since I know I can't include that with an electronic filing, I'm thinking I'll file our taxes, wait for our refund and THEN file a Form 1040-X, completing Part III "Explanation of Changes" and write that I'm attaching this document.  

Does that sound feasible??
