[ATLA] Could conjoined twins bend two elements?

Let’s say the parents are a waterbender and a firebender, so there are two elements at play. We already know it’s impossible for any one person to bend two elements. So I guess the question is would conjoined twins, in sharing a body, have the same limit?

(1) Would it be possible for one twin to bend water, while the other bends fire?

(2) Going further, would it be possible for both twins to bend both elements?

I believe it would be possible for one to bend fire, and the other water, assuming their parents were from the water tribes and fire nation, respectively. 

It would *not* be possible for both to bend both. If it were, the child would likely die before it could be expressed - the power is too much for a human spirit. Only the Avatar's spirit being bonded to Rava allows for them to bear that much power.
