For a start, I like your changes.
Some general thoughts:

A problem with the 2handed Bane Blade weapon is,that its used by Bane`s and Bane Lords.

Also,its important to consider the constr level and the gem cost,especially when altering level 0,5 gem weapons.

Personally i would prefer to agree on the exact changes for the Wraith Sword first.Then we would have a nice and more expensive weapon to be compared to for balancing reasons.

Wraith Sword:

15 Dgems,Path 3D( 25Dgems,4D before)
Construction Level: 6

Damage- 16 (+7)
Attack- 4 (+2)
Defense- 5 (+2)
Length- 3

Partial Life Drain

overpowered?

I thought the same about the defense bonis before,but Sombre had a good point about that.
I now think,some increase in def for the 2h swords,only the swords,are ok. Especially for the Wraith Sword,i think its thematic anyhow.
