Nice idea! I used to own one of those RGB to VGA converters, but as it 
didn't fit my application (*) I sold it to a friend. Usually when it comes 
to composite video one has a full colour signal so your approach would not 
be very useful, but in the PET application it probably would work.

(*) I wanted to use it with my Amstrad MegaPC, that outputs a 31 kHz sigal 
in DOS/PC mode and a 15 kHz signal in Sega Megadrive mode, both from the 
same 15-pin connector. The boards listed on eBay claim they accept VGA 
input, but apparently this is false information. When converting from 15 to 
31 kHz, the board worked well but when "bypassing" 31 kHz it produced an 
image that my VGA monitor couldn't sync to - perhaps 62 kHz or something 
equally stupid?
