So if you use a 0.25g BB and the velocity goes down(lets say 280FPS), that's still 1 Joule of impact.

So if you use a heavier BB, and say that someone would feel the BB hit them harder, it's theoretically speaking, wrong isn't it?

I mean, it's the same impact power.
You are correct. The energy generated by a particular gun is constant; lighter BB's travel faster, heavier BB's travel slower. Impact force in joules is the same.

This is incorrect. Heavier BB's actually travel slightly farther. For example, mathematically, a 400 FPS gun will fire a 0.2g BB with hop-up a distance of 187 feet. Switching to 0.25g BB's will increase the flight distance to 198 feet.
