Mordekaiser new ability idea

If Riot keeps Mordekaiser's theme as a master of metal then i think a new ability/ulti idea could be the following:

Mordekaiser - hardens himself,his armor,whatever - reflects every enemy projectile back for a few seconds.Reflected projectiles retain their original properties thus they can stun,slow,deal damage,crit whatever but can only affect the enemy after the bounce.This includes basic attacks too at least i think it should. Projectiles would travel a set distance before disappearing or disappear on the first enemy contact.

Now the hard part would be is to decide in what angle should the projectiles bounce off from Mordekaiser.

The other direction is Mordekaiser would absorb the projectiles (instead reflecting them back) powering up his next ability/ulti/gain stats for a few seconds.

Would such an ability work thematically and gameplay wise with Mordekaiser?Would the reflection be possible with the current engine?

What do you guys think?
