Actually, based on what we know, you can.
Form 1 uses basic lightsaber techniques; blocking, basic attack, etc.
Form 2 uses a lot of jabs, and flourishes with the saber to confuse the opponent. Think of fencing.
Form 3 is very defensive, uses pretty strict movements in terms of blocking. Conservative of energy.
Form 4 is acrobatic as you said, moving around the enemy a lot
Form 5 is heavy, lots of overhead strikes and quick attacks, not allowing your opponent to strike. Shien is more focused on deflecting blaster fire.
Form 6 is heavily based on the force, implementing that with combat.
Form 7 is also very acrobatic, and the most difficult to learn, also the one we know the least about.
People have studied these, and have actually figured out how to teach them and use them irl.
