Is it possible or it will be possible to have GI affecting non-static objects ?
Yes.
That’s what the light probes are for 
Ahhh ok… That makes sense XD
thanks 
But it’s worth noting that dynamic objects will be lighten by probes, but light won’t be reflected from them, so it won’t affect other objects. I mean probes are kind of cheat, they are not real part of GI system.
