Rant are all dampers created equal?

are all dampers created equal? Why does Mimaki use the tall dampers on a dx5 head, and Roland uses the small side by side dampers, and Mutoh uses the dual channel dampers? All are "based" on the same dx5 technology but everyone has a different theory... I am a little crazy so I might just try the tall Mimaki damper on my mutoh or swap in a set of the big roland dampers just to see if it changes anything. If you have tried this and know it will not to work or can provide a reason why I should not try please let me know.
