I don't think it exists.
If you go to a smaller case it will not be quite as deep and you "may" need to lay the taller eyepieces down. This takes up a slightly larger footprint in the case. I would be looking at a 1500 or 1550. The 1550 is deep enough to stand any eyepiece bar an ETHOS upright. With everything I have in the case it really is too heavy and I would split the load over 2 smaller cases.
