Should the old beyblades be rebuilt to be competitive with MFB's?

Rather simple really, The old beyblades are technically worse than the modern MFB's. Should they be re-engineered and rebuilt to be able to compete with MFB's? This would be done by adding more weight, or a faster spin speed and stuff like that.

OR, should they take the old Bit Beasts and the BladeBreakers, and build a whole new set of MFB's for them? These blades would be MFB's, which means they would also be competitive with the other modern blades.

Thanks
