I strongly doubt it. Steam already tried releasing a console alternative, Steam boxes, and they massively flopped. By and far the main reason for the Steam deck's success is its portable form factor, not the fact that it's a linux machine that runs games. It succeeded in spite of the software, not because of it.
The overwhelming majority of users are going to want either a "real" (read: Windows) PC, or a "real" (read: the same one their friends have) console.
