- Morphing spears works either by sheer will and the wielders state of mind is essential for the outcome, or by some more complex angelic rules
- Kaworu might or might not have known how to morph the spears, but his inability to do so is likely tied to Gendo taking his place and downcasting him
I would add the Spears being in an altered state (apparently by Gendo) in 3.0 should be essential to turn these Spears into Longinus. After all, Gendo needing to take this measure means he doesn't expect the two Spears to turn into Longinus only by Eva-13/Shinji and Kaworu touching these.
Also, Kaworu expected to find the Spear of Longinus and the Spear of Cassius, which he needed for his plan to repair the World. So, he doesn't think Shinji or himself touching these Spears will change these Spears either.
