Well, did some of my own research using Two Dimes (didn't realize that worked for O8, too, how cool). I guess these results may be intuitive, but helps to see the black & white numbers rather than hunches (which for me aren't reliable enough in O8 yet). Comparisons are listed with EVs shown, hands are rainbows unless otherwise denoted.

AAKQ 0.419
AA93 0.581
>>> The low kicker really beats two high kickers.

AAKQds 0.465
AA93 0.535
>>> Better to have one low kicker than all hi & dbl suited even.

AA54 0.492
AA93 0.508
>>> Better to have the lowest low kicker than two low kickers.

AA54ds 0.539
AA93 0.461
>>> Being double suited makes up for low kicker disadvantage.

AA83 0.492
AAK3 0.508
>>> Interesting, it is better to have the high kicker than the other low kicker.

I guess the conclusion is call the all-in with AA2x for sure, and probably even AA3L where L is another low. AA3x is probably an auto-call, too. All four high though, even if double suited, will be a dog to any AA with any low kicker, so probably should pass this hand if you think your opponent only moves in with AA. (Also, AAKQ rainbow is a dog to A234ds, so I guess even if you think they would move with A234, it is still wrong to call with AAKQ because your marginal fav, marginal dog, or more significant dog, but never a decent fav.)
