(Champion Concept) Grace and Teach, The Thieving Siblings

Being a pair of homeless orphans can be difficult, esspecially if you live in the crime infested bilgewater, but thats exactly what siblings Grace and Teach did, doing all they could to survive being abandoned at a very young age. With Grace being an excelent shot, and Teach being quite the swordsman, poing a gun at one, and another barrel will rest on your head.

passive: you control 2 characters at once, one a melee teach, and the other a ranged Grace. Using q to control, and using your ultimate to switch between the characters, think annie, but more complex. additionally, they share a health bar, and mana pool, if the healthbar goes down, the character that got hit last by an ability will die, while the remaining character gets restored 60% percent health. If both characters get hit at the same time and die, the remaining one will always be the one thats not being used at that moment

Q: used to control, but when one of the pair dies, the remaining gets a single use of an ability thats put onto the q. If the q is used, the R cannot be used. Grace: shoots a small cone from her blunderbuss, sending all enemies at the end of the cone. this can also be used as a disengage Teach: does a short dash, doing slight damage to anything hit, and slowing them, this can also be used as a getaway

W: Grace: Shoots a cannonball from her blunderbuss, doing damage to the targeted enemy, and doing aoe damage in a small cone behind that enemy, if the Teach attacks the same target soon after, it does another cone, and gives Teach bonus movement speed for a second or two W: Teach: Teach throws a dagger in the target direction, if it hits an enemy champion, it stops, applies grev wounds for a short time. If Grace attacks the enemy who has the grev wounds from the dagger, this will deal bonus true damage, and will restore some of the pairs health

E: Grace: Grace throws out a noosed rope onto the ground, leaving a trap, if any enemy walks over the rope, Grace yanks it, pulling the enemy a slight distance towards her. E: Teach: Teach throws himself at a target direction, doing damage along the way, and knocking up anyone in a small area wherever he ends up.

The Ult is usually used to switch between the two characters, switching out the e and w for the respectable character, but when one of them dies, the remaning character gets a single use of a powerful ability until the dead character comes back. If the ult is used, the q cannot be used. R: Grace: Grace goes full reaper, spinning and shooting, doing aoe damage for 4 ticks, and Grace getting slowed by 50%. If an enemy gets hit by one tick, the next tick they get hit by will have its damage doubled. This is a very devestating ability if the enemy stays in the range the whole time of the ultimate. R: Teach: Teach Takes his sword and slams it on the ground, doing massive damage in an aoe line forward from Teach. If this ability kills an enemy, the ability can be used again, but this effect won't repeat.

I'm sure that the idea of two characters in one champ might be hard to balance, but I'd like to hear suggestions, and possible feedback
