What about those WARC bands

I'm reading on the web (QRZ, QRZNOW, EHAM, etc.) about the amount of digital on the air these days and how it's getting loud and crowded on 20 & 40. What say we start really working WSPR on the WARC bands? They're waiting to be lit up as much as good old 20. 17 during the day and 30 at night?
