The addressing wouldn't be a question because the Massbus controller handles that.
But the sector format is a different matter. If it's designed for PDP-11 and friends,
presumably it has a 512 byte sector size. For PDP-10 or -20 use you'd presumably want
a sector size consisting of some round number of 36 bit words.

So I can't say whether they are 18 bit
compatible.
Huh? The KM11 doesn't plug into the UNIBUS (or QBUS); it's a MASSBUS device (a
solid-state storage device, actually), so it plugs into an RH11 or RH70 or
something like that. (I should work with the VAX MASSBUS controller, too.)
So the question 'is it 18 bit compatible' makes no sense.
