An idea about gravity-gravity released

[sxskr]

Gravity Released
cost 8 
When this card be played
every "gravity creatures" in the field(include enemy)
change every 2 HP to 1 ATK and every 1 ATK to 1 HP
and get "airborne"
(the maximum ATK can be transfer at most 15)
for "4 turns"

for example
animal titan change 7/70 to 15/7
Otyugh change 0/3 to 1/0

This idea is not complete yet.
can this work?
By the way im an newbie here.

Taking an elements theme and deliberately going against it is usually unpopular because it either does not synergise or  becomes overpowered running the gaps that the element cannot normally fill. Personally I feel this card is Entropic in nature and not gravity.
