you wanna make distort vision more cheaper when a discipline mastery is done?

No, that only became RAW with Black Crusade. Post-errata DH is very strict: Not only can you only manifest one power pr round (with the ONLY exception being Resist Posession), but making such a manifestation also counts as an Attack action.

Personally I prefer the BC rulings where you can only make one action with each subtype pr round, and various psychic powers have different subtypes. 

But according to DH RAW, no.

Well, that won't really help, as the one that ends after your next turn will do just that: End after your turn, before the enemies shoot back.

The only situation in which this stacking would help, is of you run into Overwatch which means you get shot at on your own turn. But this seems very situational, and not worth spending 200XP for methinks.

Not really, as there was a new discipline power introduced in Disciples of the Dark Gods IIRC.

Well, it's the right book for it at least. Sounds like something Slaanesh might approve of :)

I asked to get the input of the designers on this one, and here is what Tim has to say on the matter (including a bonus question not really related but also on Psy powers)

Rule Question:
Question 1:

The Telekinetic Shield power seems very weak compared to its siblings, and when compared to its corresponding version in Rogue Trader.

The Dark Heresy version grants just 1 single AP, with an additional 1 AP pr 10 points of overbleed. With a rather high cost, it is unlikely to grant many points.

The Rogue Trader version grants 1 AP pr Psy Rating, which seems rather more appropriate. Is this a missing element form the DH power, or is it deliberately much weaker?

Question 2:

Precognitive Dodge is also a power which seems sadly underpowered compared to its much more useful little sibling Distort Vision.

I have read the Errata, but even in its nerfed state, the minor power is cheaper, better and more versatile than the more expensive discipline power.

Should one of these powers be adjusted, or am I missing something?
