Tablo with a digital converter?

Hi, I know Tablo does not support QAM signals but if I installed a digital converter box in the coaxial line before the Tablo would it be able to detect these channels? I only get 4 OTA channels but can receive ~80 QAM and would love if I could get my Tablo to work with the channels that my service provider sends via coaxial for free. Has anyone successfully done this?

If I understand correctly, I believe Tablo will record them as channel 3 or 4 depending on the convertor box setting. You would need to change channels on the convertor box. Also recordings would have to be manual.
