SLI (two GPUs working together) is dead is the biggest issue, and Nvidia/Nintendo are not going to invest to fix it. In theory you could make the upscaler external, except DLSS 2 doesn't work that way at all, with all the vector information needing to be baked in. Unless you want to shut off the internal GPU and make a stronger external GPU that takes over when docked, but that sounds very expensive.
Switch 1 OG is downclocked in handheld so as not to burn your hands and to not drain the battery so fast it bulges. GPU clocks double once its docked when it doesn't have to worry about those things anymore. I expect Switch 2 clocks will be arrived at in the same way, with the caveat that tensor cores will activate to bring typical 1080p docked render up to 4K.
