Is it possible to change the Game console Graphics output to AV/Composite?

Not sure if you meant to edit your post to be blank, but to answer your question: yes, anything is possible with enough effort.

You would have to use another chip to decode the vector output and convert it to a video signal. Since the DACs are driven with parallel 8 bit ports, it would be simplest to tap into those rather than interpreting the analog voltages.

The device would need to monitor every coordinate sent, and plot that in video memory, and apply some kind of virtual phosphor that fades. It would make for an interesting FPGA project.
