Using the additional speakers for ambience is one way to do the
conversion. What will your host do ? Just add 4 empty channels ?
Is the plugin supposed to know it gets silence on these channels ?
Will your host add 20 empty channels to the input of the plugin
that converts a signal from an .amb file to my 24-speaker setup ?

Yes. If a host can do all that it needs no plugins. But I see no
point in continuing this.
