Interactive Live Replay & Hitpoints alteration

I have two suggestions, please consider and give your views on it -

1) Interactive Live Replay - What I have noticed is that while defending, our heroes are unable to use their ability, while the attacking heroes can. My suggestion is to allow the person to use the Heroes ability in multiplayer raids if and only if he/she is watching his village raided live.
I know this is difficult to implement due to server lags and other factors. But if this could be made reality then that would be great.

2) Hitpoints alteration - This is straightforward. If the storages are 50-75% full, increase their hitpoints by lets say 20%. If they are 75-100% full, increase hitpoints by 40%. This will make raiding tougher and help those who have worked hard to collect all that loot.. The same could be applied to collectors, mines and drills; but I don't support that thought.

So..let me know what you guys think about these two ideas.

Cheers!
