Something like that, yes, except I think it has to be a UI, not
a tense, and I'm not sure we need a new cmavo, we may already
have what we need. For example, I think we can understand {ei}
to mean "in an ideal world" (essentially the job of "should" in
English) {a'o} to mean "in my favourite possible world" and {au}
"in my favourite impossible world", or something like that, I
still haven't worked out all the details, but it looks promising.
I'd rather be sure of what we already have before bringing in
new cmavo.
