Sure, but it took about 30 years for teams to adjust to the 3 point shot, 10-15 years for player talent development, and 10-15 years more for coaching to embrace it. It would probably take a similar amount of time for teams to optimally play with a similar rule shift. Post ups and mid range jump shots wouldn't suddenly appear.
(The NBA has had the 3 point shot for 45 years, the NBA was missing the 3 point shot for 30 years. I know this board skews older, but how many people here have really firm memories of a time before 3s? Mike Brown was 9 when the shift happened, and he's one of the older head coaches in the league)
I think adjustments would happen a lot faster. It's true that a talent pool had to build up, but I don't think that was the primary reason for the slow adoption. There was just an old-school bias against adopting "newfangled" ideas - the absolute pain involved in convincing old-school management/coaching that shot efficiency was not only a real thing but actually mattered, like A LOT, was enormous.
Just going in decade-sized jumps, let's look at the percentage of shots that were threes over time:
1985 - 3%
1995 - 19% (+16)
2005 - 20% (+1)
2015 - 27% (+7)
2025 - 42% (+15)
And compare with 2PT EFG% and 3PT EFG% in the same span
1985 - .499 .423
1995 - .491 .539
2005 - .470 .534
2015 - .485 .521
2025 - .541 .539
So there was an initial adjustment in the first decade or so, which had a lot to do with increasing the talent pool for deep shooting, and then a serious stagnation between 1995 and 2015 where three-point shots were way more valuable than twos, but the league just didn't adjust. Now, over the last ten years, the league has adjusted - in fact so far that perhaps the pendulum will soon need to swing the other way. The upswing in 2PT% is pretty remarkable here and presumably has to do with teams opening up the paint to instead guard against the more-valuable three (Sacramento Kings excepted, it would seem).
But I think it's fair to say that now teams care so very much more about analytics that eliminating the three point shot entirely would cause an immediate and drastic change in both shot distribution and defensive schemes. We're just so much better at doing that stuff now, and all the management/coaches are on board. Adjustments would take months, not decades. I'd be willing to bet on it, but the experiment won't be run, so there's no point.
