David, I've done just this at least a dozen times.  Open the INIT with ResEdit,
find an INIT resource named "ShowINIT", copy and paste it into the target file,
and create/number ICON/ICN#s to accomplish the deed.

In fact, I created a joke INIT for a friend's birthday just this way.  The file
contained only two resources; the ShowINIT resource and the ICN# to be shown,
which was some cake or something. I changed the filetype to "INIT" and dropped
it into the System folder, where it worked fine.

Not true.  It is true that ShowINIT was originally written in assembler, but it
compiles into an INIT resource, which can be cut and pasted with ResEdit just
fine.  I'll be glad to mail you an example, if you wish.
