Yes it seems this is approach that Nintendo will take and something similar is very posible, but don't expect this in near future, maybe in 2-3 years.
In 2018. for instance we can expect Switch Pocket that will be smaller version of Switch, without dock and controller just for outside home playing. Later we could expect dock that will have more power or just powerfule Switch home box.
