What Krystal needs is a blend of both games. Have the staff function as a melee weapon, but include the Gatling Gun, Telepathy as a counter attack or dodging method, and even Grenades. I would do it like this:
A-Staff Swing. Krystal maneuvers the staff and strikes the foe with a quick three swings. The attack is abrupt, but powerful.
Side-A: Fire Push: Krystal lunges forward and strikes the foe with her staff. The attack has a fire elemental effect.
Down A: Staff Sweep: Krystal strikes both sides of her with the staff. Opponents on each side of her will get hit.
Up A: Staff Shock: Krystal lifts her staff upward and pulls any character who makes contact with her will get pulled into the staff and takes a huge amount of shock damage and gets launched upwards.
F-Tilt: Krystal simply double kicks upward.
Nair: Twirl: Krystal twirls her staff andinflicts a number of hits on her opponent.
Dair: Assault Heel: Krystal's meteor smash! Krystal simply stomps on her foe with the heel of her boot. While this may not seem like much, I feel like it's something that would really fit her character, since it seems like a lady-like move that would fit her well.
Sair: Roundhouse: Krystal performs a powerful roundhouse kick in midair. Direct contact will this kick will result in decent damge.
Uair: Flip Kick: Krystal does an upward flip kick in mid air, a move meant for keeping your opponent up in the air. Can be a knockout move when opponent's damage is high enough.
Neutral B: Gatling Gun: Krystal charges a powerful Burst from her Gatling Gun. When the attack is fully charged, she shoots out a burst of laser rounds that inflicts a good amount of damage. The attack can be put away when fully charged.
Side B: Freeze Charge: Krystal charges in place as her staff begins to emanate a fog. Once she releases, she charges forward at the opponent. If the opponent is hit, they will be frozen solid and sent upwards. This would be a great setup for some combos in the air.
Down B: Staff trap/Staff Quake: If Krystal is on the ground, she smacks the tip of her staff against the ground and any opponent in the radius will fall into a pit trap. If she is in the air, she will charge at the ground with her staff and cause a shock wave that will damage anyone in the radius.
Recovery: Rocket Jump: A chargeable recovery where Krystal rides her staff like a skateboard while it propels her upward. The longer it's charged, the farther it will go.
Grab: Krystal simply grabs the opponent. If no throw takes place, Krystal will simply kick the opponent.
FGrab: An interesting move. Krystal straps a grenade to her opponent and pushes them away. The explosion is minor, but still causes damage.
DGrab: Krystal Steps over the foe and shocks them with the staff.
UGrab: Krystal kicks her foe in the air and shoots them with the uncharged Gatling gun rounds.
Final Smash: Cloudrunner Assault.
Krystal sends out a distress signal to an old friend. On screen, she will stand in place and say, "I need your help." Soon, the cloudrunner from Adventures will swoop in pick Krystal up. The cloudrunner will shoot massive fireballs at the stage at a slow rate, but will also be able to attack foes with it's claws.
So that's that.
