Pathfinder 1E Using Trailblazer's unified/multiclass spellcasting in Pathfinder?

[VelvetViolet]

Multiclass spellcasters don't work very well in Pathfinder. Higher level spells are sacrificed in favor of doubling the number of lower level spells. In the Trailblazer rules, spellcasting relies on a base magic bonus similar to a base attack bonus. BMB is used to determine caster level and spells/day rather than class levels. Every class has a BMB of lvlx1/3 (barbarian, fighter, rogue), lvlx1/2 (monk, paladin, ranger), lvlx2/3 (bard), and lvlx1 (cleric, druid, wizard, sorcerer). Multiclass spellcasters thus use a single spells/day progression that they can use to prepare any spell on their classes' lists they could normally cast at their respective class levels (e.g. a ranger/wizard could prepare his ranger spells in his wizard slots) rather than having separate sets of caster levels and spells/day. Prepared spells are separated into readied spells and spell slots (equal in number), so a readied spell can be cast multiple times if sufficient spell slots are available. Sorcerers now ready spells like wizards do, but they receive additional spell slots, while Wizards receive additional readied spells.

Would this system work for Pathfinder?

I'd need to go over it again to be 100% certain, but my suspicion is that it would. The methods of spellcasting in 3.5 and Pathfinder are identical in their specifics; as such, using the Trailblazer method in Pathfinder, rather than 3.5, should produce the same results.
