To add long s ligatures (in my case, for use with Adobe Caslon Expert
fonts).

Yes, because either I use multislot, and then end up overriding rather than
adding to slots, or I don't use multislot, in which case the \inputetx{t1}
will add to the slots I want to override. I can't both override and add to
slots either with or without multislot.sty.

I want to add to the existing definition.

You may be lucky with how vptovf deals with multiple definitions here.

Exactly, I'd rather not rely on this.

I want to add a ligature rule to an existing glyph, i.e.

\inputetx{t1}

\setslot{some glyph defined in t1.etx}
  \ligature{...}
\endsetslot

I don't think so, as you can't read a patched version to see how it's
different. A patch is both easy to read, and easy to apply.
