extended display for Edge on TV/Tablet/mobile?

would it be possible to create something like an extended display for Edge on TV/Tablet/mobile?

the idea himself comes from Xert Remote Player:

The background, i do a lot of Indoor Training, but my problem, i have eye glasses i cant wear at indoor training because it's to hot, so i can't read my display on my Edge, so it would be nice to have an extended display browser based.

yes, i can buy a Xert Licences, or Zwift or similar, but i think it's to expensive when you use it only as a Extended Display, because my Edge can control the Smart Trainer,

anyway, i know for this feature you need something to sync between your Edge and a Webservice, where you are registered, but i think it's possible to offer with smaller price as all those other Indoor Software, could be a good and small business?
