Marco is right, a 'uchr' would be easier than an input method.

See page 38 in the same document. The data format is described there.

There is not a more recent version, unfortunately. We are working on
improving our documentation.

Yes, the 'uchr' format is the same for Mac OS X.
Our 'uchr' resources are created using an assembler. It's the only tool we
are aware of that can fill in the offsets the 'uchr' data structure
contains. We don't have a custom 'uchr' editing tool at this point (we would
love to have one...).

I don't believe so. Resource ID conflicts should be resolved either by an
installer or when you drag it into the System file.
I hope this helps...
