An active/stative distinction in Timucua?

I've been investigating a possible Active/Stative distinction in Timucua.  At this point, I have only looked at 1st plural agreement.  

The patterns:

A   V-nica = 1st pl subject

B  ni-V-bo = 1st pl subject

The B pattern is identical to what is always found for a 1st pl object -- ni-V-bo.

Verbs that seem to be in the A group include

• pueno 'come'
• nate ... mani-si  'pardon'
• tamalo  'ask, entreat'
• abosini 'be (pl. subject)' 
• iso 'do, make'
• patu 'be cold'
• toco 'come out'
• nahiabo 'know'
• lapusi 'request'
• areco 'make'
• hime 'return'
• hoboso 'receive'
• quachi 'teach'

Verbs in the B group include

• balu 'live'
• ara 'be many'
• nihi 'die'
• ni 'suffer'
• fari 'return'
• abosini 'be (pl.) subject'
• ini 'be'
• chebe 'be lost'
• nurabo 'tell a lie'

The semantics of this are not straightforward, but most of the verbs in group A are agentive, and most in group B are non-agentive.  (Exceptions -- nurabo 'tell a lie'; patu 'be cold'; nahiabo 'know')
The only verb I have found so far with both A and B inflection for 1st pl is abosini, which seems to be a kind of auxiliary.
