No reason they won't work but the relationship between the height of the 044 and the listener's ears is always important in mid-field use. If it's an issue for you, you can always try tilting them a bit.
I'd go with what you have and play with position and room issues. I've always found on the better JBLs that attempts at improving the performance through substitution of non-stock components does not generally create improvement. If you're messing with crossover caps and trying to save money, you might want to modify one without removing your ability to return it to stock, and then compare it to the stock system and let your ears tell you if it was money well spent—or perhaps even a step backwards. Remember, too, that your ears are funny instruments and so is your brain. You might wish for any improvement enough to find one that doesn't exist. And listening to one voicing over time may color your ability to make an objective observation in any A—B comparison. Give your ears time to adjust before you switch sound sources.
Of course all this is just my opinion and I'm basically a Luddite, don't own any L100s that might benefit from Internet pros who seek to change their voice, and love most of my dozen-or-so JBLs for what they are and actually revel in their differences. (No Harman-brand pun intended . . . well, maybe!)
