I doubt you get any real quality improvements from increasing sampling rate for Wii since it most likely uses 27MHz pclk and standard timings for all commercial games (homebrew/emulators may use special timings, though). By bumping up sampling rate from native (858 for 480i/p standard), the result will just intergrate more of the characteristics of the underlying analog signal. It might soften the image which could be subjectively positive, and some displays may apply less processing if horizontal width is higher, but it won’t recreate Wii framebuffer content as faithfully as native sampling.

Samplerate adjustment has a limited range (typically from 0.5x to 2x from the default) in all but passthru mode since FPGA PLL’s lock range is not unlimited.
