I've found a couple of GBA header editing tools, but nothing that will work with GB/GBC ROMs.

Does such a tool exist?

Edit- for some reason I overlooked that you said editor and have just given you a list of viewers. I will leave it but I do not know of any actual editors or even anything to fix it up after you attack it with a hex editor- http://nocash.emubase.de/pandocs.htm (it is down right now as the site has been having serious issues for a few months now and comes and goes) but loads of places will still have them if you search for GBC pandocs and it does appear to be cached. Sadly I do not know of any program that will redo the header hash although it is detailed in the docs although there probably is one and most emulators will probably just flag it and carry on if the hash does not match so it is not a great worry there anyway.

GBX-NDS Header Viewer is probably closest to what you want
http://www.no-intro.org/tools.htm has it.

There is also http://www.romhacking.net/utilities/24/ but it might not be quite as nice to work with.

I know of nothing that rivals the likes of NDSTS/ndshv or GBATA though.

I attacked it with a hex editor. So far no problem as long as you attack only in that 15 character space.
