Actually I don't think it's worth the trouble if you don't have very good
reasons. You'll probably loose much quality of the sound, because the phono
amplifier tries to RIAA-correct the input signal. That is, it will amplify
the bass and attenuate the treble.
  Another problem is input sensitivity on the phono input. It is much lower 
(let's say about 2 mV), and the CD-player may give up to 1000 mV.

Your question was, if there were any commercial products available. I don't 
really know, but I haven't heard of any.
