Modify MTX crossover ? ?

Hello all,

I have am MTX HTX V2 electronic HP/LP crossover which has caps and some resistors I would like to replace. I am wondering if anybody here has added a circuit which makes the HP
slope 24db instead of origional 12db.
I also see that the audio passes through one 4013b and two 4071b.
Those are listed as flip-flops, I can include pictures if needed.
What would you other anal-retentives do with this one?
Mod it, or throw it away and buy a better one?
