Differences in diatonic and chromatic reed orientation

Hi, I have noticed a difference in how the reeds are riveted to the reedplate on two Hohner chromatic and diatonic harmonicas that I own. On the chromatic harmonica all the reeds are riveted to the reedplate at the front of the harmonica (where your mouth is), but on the diatonic the top reedplate is riveted at the front and the bottom reedplate is riveted at the back of the harmonica.
I have also looked online and seen images of diatonic harmonicas from other brands that are opposite to the diatonic I own, where the top reedplate is riveted at the back of the harmonica and the bottom reedplate is riveted at the front.

I’m attempting to design and manufacture a custom reedplate using reeds from a broken 16 hole chromatic harmonica I own, and I was wondering if it matters which side of the harmonica the reeds are attached to the reedplate? If anyone has any info on this it would be greatly appreciated.
