AES50 stagebox for lines

Is it just me or would it be really useful (and cheaper) to have an AES50 stagebox dedicated to line inputs? When you keep collecting synths – which just continues to get easier and easier – you end up with an input requirement that’s hard to fulfil. Stageboxes like the SD16 are cool, but do I really need more mic preamps? Can you imagine how many more inputs you could fit on a box if it was all quarter inch?
