Ideas for Future Champions/Perks

So I have two ideas that "might" make a good fit for some later season of TFT

War-Machine:

Champions- Battlecast Kogmaw, Battlecast Skarner, Battlecast Urgot, Battlecast Vel'koz, Battlecast Xerath, Battlecast Cho'gath

Perk- 2; War-Machine Units will self repair for 10HP per 3s for every War-Machine unit on the field. 4; War-Machine Units will self repair for 20HP per 5s for every War-Machine unit on the field. 6; War-Machine Units will self repair for 30HP per 7s for every War-Machine unit on the field.

[Note: Possibly tweak it so these units can not equip items that grant life steal or hp regen. They can however still be effected by Redemption]

Reaper: Champions- Reaper Soraka, Reaper Hecarim, Reaper Karthus

Perk- 3; When an enemy unit dies, Reapers will harvest their soul, adding 10% of all their stats to the Reapers for the remained for the fight. Stacks up to 3 times.

I did not include unit costs mainly because I'm not sure how to figure that out.
