Characters attack powers up on a certain map

[Madara Uchiha]

I'm just consider this, but I want to make a character who becomes stronger on certain backgrounds.
For example, a sand man who is on a normal map performs simple average attacks. However if they are on a map which has sand there attacks dramatically increase, making them more powerful.

I was thinking of using the perspective tag in the bg data to summon out a ball which reacts to my character's attack and power-ups his attacks -by responding to an itrkind8.

Theoretically this seems possible and I can't think of anything which would prevent this. I just want to know if there are any flaws in this idea.
