I was thinking of arcade-izing a Colecovision (which can easily be modded to composite BTW) and I was wonder if there's a way to connect composite video to a standard arcade RGB monitor?

I now there's a TON of adaptors for doing RGB to composite, VGA etc, but I've never seen anything for going the other way.
 
I'm pretty sure you could find something to do it with, but the real question should be why?

Composite video is the lowest quality video there is. The image is blurry, the colors are very inconsistent, you get lots of artifacting, etc. Those problems are not from the television set you connect the video signal to, they are the result of the video signal itself.

If you really want to try, check out some of the later versions of the X-RGB device. I know they can take a compisite signal to VGA (I've done it), but I'm not sure if they will go to 15khz RGB.

If you just want to do that pretty easily, and you don't mind it being about 13", find a Commodore (1084, 1084S, 1702, etc.) monitor. I think every single one of those have composite inputs.
 
If you are just looking to put it in a cabinet why not just mount a 19" tv in the cabinet and not worry about video translation at all.

The only way I can think of is the way they did it in the Dragons Lair laser games which uses a NTSC to RGB card. Dragons Lair came with 2 types depending on which monitor you had. Some came with a G 07 with the rectangular Electrohome NTSC card and by far the easiest one to get working with and standard RGB monitor, just needs a 15 volt DC power source.
The other is the square Wells Gardner NTSC card which will only work with the 4900 series monitors, something about a blanking signal for the sync. It can be made to work with newer monitors but it's a real PITA.
My advice is just put a 19 inch TV in the cabinet that has a video input that will power up in the video mode when power is applied. That's what many people did with their Dragons Lairs. Their are some TVs that will do this, I think they pull them apart and put the tube in the monitor bracket. I am sure you can find plenty of info over on Jeff Kinder's Dragons Lair Project.
