All stores can be found here: bioui.ini > sfxgamecontent > sfxguidata > store
Here you will find subsections, corresponding to each stores in the game ("asari" is nos astra, "batarian" is batarian state arms, and so on).
Each of those "stores" have a subsection called "storeitemarray = (multiple)". In this subsection, you will see items available from the store. Remove the value: "PlotUnlockConditionalID=XXXX, PlotPurchaseID=XXXX" from desired weaponmods.
For instant purchase access to level 5 SMG damage upgrade, "asari -> storeitemarray = multiple"
Modify the value: (ItemType=TYPE_MOD,ItemClassName="SFXGameContent.SFXWeaponMod_SMGDamage",BaseCost=4000,PlotUnlockConditionalID=1535,PlotPurchaseID=21304)
When in game, you will be able to purchase the SMG damage mod from lvl 1 to 5 instantly from Nos Astra Sporting Goods.
Can you provide step by step points on how to edit in NG+?
Edit: Managed to edit a save to NG+ via the Gibbed ME3 editor.
It's under plot, known variables, New Game + Count.
Using the r53_b66 version.

Edit2: Not all weapons seem to be upgradable to X, atleast not just after Thessia, some are limited to VII at the moment. Might be unlocked further on.

Yeah, not sure why but from what i've noticed if the weapon is one you pick up later on (rather than from a shop) then the weapon will go to VII and when you pick it up from wherever it will then give you the last few upgrades.
All available bonus powers can be found here: bioui.ini > sfxgamecontent > sfxgamechoiceguidata > storedata > bonuspowers > bonuspowerarray = (multiple)
Remove the ",PlotUnlockConditionalID=XXXX" or set "XXXX" to "-1" on the desired powers to unlock them.
A more apt option will be to replace the XXXX of desired power with XXXX of a power easily/already unlocked.
For example - one may edit the reave power to become- (ItemType=TYPE_POWER,PlotUnlockConditionalID=1281,BaseCost=3000,ItemClassName="SFXGameContent.SFXPowerCustomAction_Reave",ChoiceEntry=(srChoiceName=314878,srChoiceDescription=314879),Priority=9,BaseCost=5000,LargeImage="gui_codex_images.Store.STO_BonusPower_512x256",SmallImage="GUI_Icons.Notifications.NT_Store_256x1286"
XXXX originally was 1276 but i replaced it with 1281, allowing it to be unlocked along with fortification(unlocked after one good long paragon conversation with Mr. Vega)
To change the cost of switching bonus powers, go here: bioui.ini > sfxgamecontent > sfxgamechoiceguidata > storedata > bonuspowers > storeitemarray = (multiple)
From here, change "BaseCost=5000" to the value of your choice.
Swiching the XXXX to -1 didn't work. Swiching the XXXX to an already unlocked power didn't work too. The plotunlockid for the bonus powers isn't were you pointed it's in biogame.ini/sfxgame/sfxprofilesettings/bonuspowerunlockdataaray=(multible)
