I've done it.

Firion: HP is at 2264 and MP is at 294. Weapon skill is at lvl. 8 , Cure at 6, Ice at 5, Bolt at 5, Blink at 3 and Life at lvl.4

Maria: HP at2022 and MP at 308. Weapon skill at 6. Cure at 6, Ice at 5, Fire at 5, Life at 4 and Shield at 3.

Gus: Hp at 2465 and MP at 255. Weapon skill at 8. Cure at 6, Bolt at 5, Berserk at 3 Life at 4 and Shell at 3.

It took me 13:22mins. I didnt take Warp cause im gonna get it in the cave and I didnt get Faze cause I dont need it.

I got Mindu and my HP was at 700. I leveled up my HP using Swap and they all(exept Mindu) would gain HP. I leveled up MP by casting Faze, thus lowering my MP then getting more. I got my spells higher by going directly south(down) of Altair. When you get directlly to the bottom and see new land(but need a ship to get there) stop and save. You encounter Mysidian monsters there. You get a lot of money this way. You can shoot spells at them to make them higher(they got ressistances and a lot of HP).

Thats how I did it. Fell free to do the same thing.

P.S. I didnt copie off of anyone, so dont make false accusations.
