Could be these custom chars balanced?

[Lugrandbeurre]

Hey, I really love to play the Heroes in the LNOE, but with some friends we'd like to play our "alter-ego" character
We've designed some of them, but i'd like to have some suggestion plase, as I fear that some abilities could be unbalanced

Here we go!

Charlie student - strange 1 wound
I've bought on ebay! - Instead of searching, discard a card. take one any card from the hero deck on 3+. May not take guns, scenario item or "Just what i needed" cards.
Hide! - May cancel any fight he is in on the roll of 4+
Youth -May give up a Move Action to Fully Heal.


MD. Ciaky - female medical 2 wounds

It's an Emergency! - As long as MD. Ciaky is in the hospital, she may Search and move.
Moving through the patients - Ignore any number of zombies during movement on 4+. On 1 end the movement.

Tobia the Magic Player - student strange 1 wound

Mulligan: may re-roll any dice. Each time add a -1 penalty (cumulative for the same dice).
Hexproof: may not be a target for zombie cards
Youth -May give up a Move Action to Fully Heal.
