Would it make sense for a subject/agent noun to take the nominative case if the verb is stative (transitive or intransitive) and the ergative case if the verb is dynamic (transitive or intransitive)?
I have a problem here, because by definition statives can't be transitive. [wikipedia does use the example '[be able to] play the piano', but I think that's something different, and it isn't covered by wikipedia's own lists of categories]. They can be bivalent in some languages (like "I hear the clock" - it's not transitive because the clock is not actually affected in any way, in in many languages you'd have to say the equivalent of "I hear [from/of] the clock").
It's certainly not unusual to mark transitivity through differential case marking. Usually there'd be the option to do this with intransitive forms of dynamics as well - so "I have eaten" would take different marking from "I have eaten [it]". But maybe your language just doesn't allow detransitivisation without conversion into a stative (i.e. there are no dynamic intransitives in it).
Differential marking using two different forms of non-absolutive (rather than just erg-abs) seems stranger, but I suppose plausible. After all, quirky subject is a thing.
I'm not convinced you have an ergative, though. If, with dynamic verbs, the "ergative" is used for the subject of intransitive verbs and the agent of transitive verbs... that's the nominative case, surely?
And would it make sense for inanimates to possess nom-acc syncretism but maintain a separate ergative case? My rationale is that the ergative case is also possess instrumental/secondary object and ablative functions.
So let me get this straight with examples:
1. the water is cold: water-CASE1 colds
2. the man understands: man-CASE2 understands
3. the water surrounds the cat: water-CASE1 surrounds cat-CASE1
4. the man likes the dog: man-CASE2 likes dog-CASE1
5. the rock falls: rock-CASE3 falls
6. the dog barks: dog-CASE3 barks
7. the rock crushes the cabbage: rock-CASE3 crushes cabbage-CASE1
8. the cat bites the dog: cat-CASE3 bits dog-CASE1
This doesn't seem inconceivable to me. But I do think you've mislabelled your cases!
CASE1 here is obviously an accusative, and CASE3 is clearly a nominative. The only wrinkle there is that inanimate subjects take the accusative in low-transitivity (stative) contexts, which seems very believable. [both low-animacy subjects and low-transitivity verbs will tend to 'de-subjectivise' the subject - make it less like a prototypical subject]
The odd bit is CASE2. This case is only used with animate subjects of stative verbs. That maybe makes sense, specifically because it's paradoxical: animate subjects are high-transitivity but stative verbs are low-transitivity, so it's believable that a language would find the juxtaposition odd and not be willing to use the normal nominative in these instances.
In isolation, without looking at the wider case system, I would call CASE2 the "dative", because its semantics are fairly dative and the dative case is often used in exactly this context in other languages (eg German, Spanish).
A follow-up question would be whether dative subjects in this language are always true syntactic subjects (as is usually argued for Icelandic), or whether they are actually indirect objects treated peculiarly with implied subjects (as is traditionally argued for Spanish, "me gusta", etc), which would depend on a wider range of behaviours.
