It did not work with 16-bit images because it was an older version of
the plugin. What you can do is download the ImageJ source code and
convert the internal plugin that implements Image>Color>RGB into a user
plugin. Download the ImageJ source from
<http://rsb.info.nih.gov/ij/download/src/>, copy the file
source/ij/plugin/RGBStackMerge.java to the plugins folder, rename it
RGB_Stack_Merge.java, change the class name from "RGBStackMerge" to
"RGB_Stack_Merge", and change "package ij.plugin;" to "import
ij.plugin.*;". You can use Plugins>Utilities>List Commands to find out
how commands are associated with internal plugins.
