Technology incoming!
First off, random pit facts. The the direction you hold when the pits explode (and hit the opponent) determines whether they pull them towards you or push them away. Useful for the aerial pit loops. Doesn't seem to affect pushback on block.
Second, mixups! Hato has a nice little setup that has the potential to lead into enormous amounts of damage. Examples:

http://www.youtube.com/watch?v=ZgE21WrQW7Y#t=1h19m50sHere he goes for the fake crossup. This option is limited because you can't get in the corner anymore and the pits aren't used.
So I went in the lab with the above information and this is what I came up with:

Info about the mixups and confirms shown in the video:
Setup 1:
2AAA5B2C delay 4C(2)623B 2C623A j.8 j.22A j.236A drift outThis is the setup I go for most often when the opponent is in the corner. The following mixup is very hard to react to and gives solid damage. Your options are the following:
j.C (whiff) 5B5C623A j.9 j.22A j.C land j.BC dj.BC ATFake overhead into damage combo. You can go into Momiji loop or second mixup instead.
airbackdash j.C / j.C (whiff) 5B5C4C(2) j.BC dj.BC ATCrossup overhead or crossup low. Strong option, as crossup destroys DP inputs.
In both hitconfirms you want to omit any A's as they lower the damage. 236C can be used to increase it even further. There needs to be a slight delay between j.BC and dj.BC in the out-of-corner combos.
Setup 2:
2AAA5B2C delay 4C(2)623B 4C(2)623A(1-2)623C j.8 j.22A j.22B623C must hit once only, after the wallbounce, so you end up in the corner. The A pit might need a slight delay on characters with slow wake up speed to not make it explode early. From this position you have your two airdashes to trick your opponent into his death. From my testing, double airbackdash into j.C / j.C (whiff) 5B is the strongest form. However, the mixup itself is not as good as the first one, as holding back can make them walk away from you and screw up the spacing. You can airdash forward then backward to end up outside, but it's not that ambiguous, and you lose the pits.
Hitconfirm off j.C hit is:
j.C land 5B5C...Hitconfirm off j.C (whiff) is:
j.C (whiff) land 5B ... 5B5C...Combos you can go for from the above hitconfirms: (damage on VSion, unreduced)
...214[A] sj.9 j.22B j.22A j.C land 5B5C4C(2)623B (~7600, easiest IMO)
...214[A] sj.9 airdash j.C land 5B5C4C(1)623B 4C(2)623B x2 (~7200, styling)
...j.9 slight delay j.22A j.C land 5B5C4C(2) 2C3C623B x2 (~7900, no delays because of gravity)You can stick 236C in there for even more damage.
And a better 623C confirm (might be character specific)
623c j.22C airdash j.C land 3C j.C dj.BC ATPS. If you land this you can be a REAL F-VAKIHA!

The other way is the 623C setup, but there are better combos that deal the same damage without giving them free max. 
The timing of 4C should take the opponent's weight into account, as if they're too high 623A will whiff, and if they're too low, the first hit of 623C will hit, ruining the setup. On the bright side, this setup removes the chance of igniting 22A if done too early, because the opponent will be invulnerable from the 3 groundbounces/wallslams.
