The cost of the backplane will probably be prohibitive.  Vector makes
a six slot, spaced at 0.800" in 3U size - PN VMEBP6J1  The last price
I had on it was around $200 as I recall...

I need to look at the Aria case, but it might be possible to still fit
the 6 slot into the case.  A six slot backplane 3U wide with 0.800"
spacing would be less than 150 mm long (<6").

I think the important demension is the 3U width.  The height of the
plug-in cards can vary I would think.  3U100 was just a choice based
on area vs cost.
