Yes, this is a great idea, maybe some kind of module design... I can't put this into words
It's not a great idea if you want to keep the cost at some sane level (people were already worried about the cost of the riser). Dondan paid something like 3k for the prototype and what you are asking is basically the same. Not sure about you but I can't even think of spending that kind of money on a case even if it has all the tiny details that I would like.
Needs to be some balance between function and cost considering the small market size.
