It would still be a hybrid, you take it home and plug it into a dock. Just the form factor would be different.
Labo can do VR but not with a head mounted/supported headset ... you can see Labo makes a person hold the Switch with their arms to their face ... this is because the system is too heavy and probably would be too front heavy for little kids especially.
A fold out Switch 2 could solve this problem by simply having the lighter screen portion detach, imagine you could remove the top half of your 3DS ... it's not hard to think how light just that section would be. And you can integrate a small battery behind the display too. Slide that into a dedicated VR plastic headset that Nintendo could probably sell for $99.99 w/game included and voila ... now you got yourself a very nice, light VR/AR setup that's user and kid friendly.
