What if Veigar's spells interacted with his wall?

First off, I am not here to discuss whether or not his E changes were good or bad. I have my own thoughts about the changes (I agree with them) but I understand why Vei players feel short changed. If they can land the stun, they can still land their combo - but what if they don't?

So I had a thought.

What if Veigar's spells could interact with the wall or the space inside the wall, to make it more interesting if you missed the stun? Now, this is assuming that they don't just blink out of it; in that case, you're still just S.O.L. - this looks at cases where they get trapped inside the cage (But Kouga why wouldn't they walk -out- instead of in? Shut up I'll get to that)

Let's say that Veigar's abilities did something if they passed through his wall or entered the space inside the wall. This would allow Veigar to still have an empowered interaction with a Champion, and it further compounds that Veigar fantasy of "You Are Trapped In My Cage"

Q: Maybe it makes it wider, or go further, or adds another pass-through (so it would hit three targets instead of two). Or maybe the projectile splits into a fan like \ | / and splits into three? Some kind of empowered effect.

W: What if his W had a wider impact radius if it hit inside the wall? Maybe it just gets biggers, so its easier to hit. Or it drops faster, with a shorter delay. Or maybe it has a second impact after the first.

R: Oh hell no, I'm not touching his R. It's already stupidly strong so I don't think it needs love..

This, I think, adds options to Veigar's gameplay pattern and makes it much more engaging. There are few caveats:

1. Veigar's damage is already strong if he lands his combo, but the biggest complaint is that if you can't catch them with the stun itself, its hard to land his other skillshots. So this shouldn't necessarily effect single-target damage as much as it should effect the hit zones. So it should not, for example, make his Q deal more damage. Instead, by making it branch out or make it wider or farther, you simply make it easier to hit a target in the cage. This might increase his overall damage in the lane - i.e., if you let his Q hit 3 targets instead of 2, Veigar can deal more total lane damage and maybe get more stacks in rare circumstances. But it wouldn't change his 1-to-1 damage output.

2. The player inside the 'cage' still needs some kind of reaction. So we have to find the line between easier to hit, but still juke-able. We want to avoid simply making the Cage a Kill Zone by making the abilities completely unavoidable.

This lets Veigar feel powerful if he traps someone inside the cage, and he doesn't feel so bad about missing the stun. In fact, this actually makes his E more engaging overall. Do you try to land the stun on the edge? That makes it more likely they can "just walk out". But if you plant them directly in the center of the ring, it makes it much harder for them to make it out, and so you can instead use these other interactions.

Additionally this opens up his team fighting - if you drop that cage on the enemy team, you can really increases his teamfight impact. No longer is he purely about nuking the one AP carry.

I think this would be the kind of "compensation" that Veigar deserves. It makes him 1) More interesting to play as, 2) more interesting to play against, 3) gives him more options than the very binary "stun/no stun" and 4) it opens up additional play patterns all while 5) not breaking his single-target damage potential, and 6) adding to his teamfight potential.
