Personally i would realease docked mode only much stronger switch2, we know already switch zelda's run in 1440p60 on switch2 which means its still far to weak to do 4k60, so i would realease 3x more powerful stationary "switch2 compatible" console for home users only.
I know there is market for that coz some ppl never take their switch away from under their tv spot, thats the reason we got switch pr0 controller and switch2 pr0 controller after all.
3x stronger "docked only switch" would be bit below base ps5(but still over 2x more powerful from xbox series s), so its perfectly doable since ps5 launched 4,5years ago, no reason for nintendo to not launch similary powerful console 5 years after if they would be willing...
It wouldnt affect gaming division trouthput since it would work with same games, just upped resolution, just like ps5 and ps5pr0(and previously ps4/ps4pr0, xbox one s/x and series s/x worked), it would simply be "pr0 version of switch2 docked mode only" aka ps5pr0.
It wouldnt sell gangbusters, probably 10-20% of total switch sales, but option for homeboys would be nice, on top we would have pr0 version for marketting purposes and to see how those games gonna look/play "maxed out".
