New Mechanic - Physical Shield

Today I was watching a league game and noticed a Morgana spell shield.  I liked that it wasn't just a normal shield, that it stopped disables and only absorbed spell damage.  I liked that it wasn't white on the health bars but green.  So I started thinking to myself, "What other kinds of shields could there be?"

And I thought up an idea of a new kind of shield, similar to a Morgana shield, but instead of magic based, it would be physical based.  The color on the health bars could be a different color as well, I was thinking perhaps green orange or red.  And instead of stopping disables, it would stop a different brand of debuffs, such as resistance reductions and vision debuffs.  Instead of absorbing all damage or just magic damage, it would absorb physical damage.  This new ability could be given to a new champion or perhaps an old one during a rework.

Here is the description of Morgana's shield:

ACTIVE: Places a shield around target friendly champion for up to 5 seconds, absorbing magic damage and preventing disables while the shield holds.

Here is what the new move might look like:

ACTIVE: Places a shield around target friendly champion for up to 5 seconds, absorbing physical damage and preventing vision/resistance debuffs while the shield holds.

This kind of mechanic wouldn't be game breaking in any way.  In fact if you were to compare it to Black Shield it has a much smaller impact.  However it's something new that might be interesting, especially if it was given to a support.
