Pony Fantasy VI Remake

So, this is another more complex one, regarding equipment that boosts HP and MP by percentages. A lot of equipment pieces in my hack boost HP or MP to encourage party diversity (unicorn, pegasi, and earth ponies have different stat specialties, their exclusive equipment boosts their specialized stats). Looking at this coding, would it be possible to set Bit 15 to the 12.5% boost? That way, when a 12.5% equipment piece, and a 25% equipment piece, are used together, they trigger the 50% boost, giving further incentive to use the specialized equipment together for a stronger combined boost. Or I am misunderstanding the code and the game doesn't check for these bits across different equipment pieces?

Code:

(Apply percentage boost to HP or MP.  Bit 14 set = 25% boost,
Bit 15 set = 50% boost, Both of those bits set = 12.5% boost)
C2/283C: DA           PHX
C2/283D: 0A           ASL
C2/283E: 2A           ROL
C2/283F: 85 EE        STA $EE
C2/2841: 2A           ROL
C2/2842: 2A           ROL         (Bit 15 is now in Bit 2, and Bit 14 is in Bit 1)
C2/2843: 29 06 00     AND #$0006  (isolate Bits 1 and 2)
C2/2846: AA           TAX         (and use them as function pointer)
C2/2847: A5 EE        LDA $EE
C2/2849: 4A           LSR
C2/284A: 4A           LSR
C2/284B: 85 EE        STA $EE     (all that crazy shifting was equivalent to
                                   $EE = A AND 16383.  gotta love Square =] )
C2/284D: 7C 59 28     JMP ($2859,X)


C2/2850 generic boost calculation
(Boost A by some fraction, if any)
C2/2850: 7B           TDC      (enter here for A = 0 + $EE)
C2/2851: 4A           LSR      (enter here for A = (A * 1/8) + $EE)
C2/2852: 4A           LSR      (enter here for A = (A * 1/4) + $EE)
C2/2853: 4A           LSR      (enter here for A = (A * 1/2) + $EE)
C2/2854: 18           CLC
C2/2855: 65 EE        ADC $EE
C2/2857: FA           PLX
C2/2858: 60           RTS

C2/2859 pointers: boosts formulae
C2/2859: 50 28  (A = A) (technically, A = $EE, but it's the same deal.)
C2/285B: 52 28  (A = A + (A * 1/4) )
C2/285D: 53 28  (A = A + (A * 1/2) )
C2/285F: 51 28  (A = A + (A * 1/8) )
