Well as people probably know, I don't believe C. elegans can be

ants, and they're massively more complex creatures.
I think personally that C. Elegans, and Planaria (!), even amoeba, are conscious,
although very plausibly not self-conscious.
I tend to think since 2008 that even RA is already conscious, even maximally so, and
that PA is already as much self-conscious than a human (when in some dissociative state).
But I don't know if PA is more or less conscious than RA. That depends of the role of
the higher part of the brain consists in filtering consciousness or enacting it.
But it probably won't be long before we simulate a mouse brain in toto
- about 2 decades is my guess, maybe even less given enough dollars -
then we're definitely in grey philosophical territory :).
I am slightly less optimistic than you. It will take one of two decades before we
simulate the hippocampus of a rat, but probably more time will be needed for the rest of
their brain. And the result can be a conscious creature, with a quite different
consciousness that a rat, as I find plausible that pain are related to the glial cells
and their metabolism, which are not taken into account by the current "copies".
So now you agree with me that there are different kinds and degrees of consciousness; that
it is not just a binary attribute of an axiom + inference system.
