Then while they are flailing at it the thing would be knocking the lot out for half the day (being about the strongest poison I've yet seen).

I'd say lower the effectiveness of its poison or the party is going to be wiped out.
How much would you lower it? I mean, I like the unconsciousness bits, because then they (and the associated mimic) can feed.

What if I were to take away its natural armor bonus instead, lowering it's AC to 17 (17 touch/14 flatfooted)?

EDIT: And/or make the poison an initial of 1d6 Con, with a secondary of paralysis/unconsciousness for 2d4 hours?
