I doubt it. Refurbishing and selling original hardware is still likely to be much cheaper than the engineering effort required to build one from scratch.
The Wii is old enough that modern commodity hardware can emulate it well enough that it almost indistinguishable from running games on the actual device. Wii clones already exist as emulator boxes and that will continue to be the most financially sound way of producing clones.
If this leak were to include design specifications of more modern hardware (such as in the Switch) I think you _would_ see some good clones in Shenzhen in less than a year.
