I dunno. Most games today that work with gamepads virtually require analog sticks, and if you weren't going to use them because the game you're playing doesn't support them, then you just don't use the ones you have.
This would basically be a small-scale money sink for Sony, and they'd probably struggle to sell over 2,000 of these globally. From the time it's announced to the time it's released, the harsh fist of reality would have crashed down on 99% of people who might have gotten revv'd up by the nostalgia factor. Unless it was available literally 3 days to a week after it was announced, people would realize they don't actually have a use for it and nobody would buy it, preferring to buy a dedicated gamepad that actually does things.
Neat idea, but there'd be no way for Sony to make money on it.
