Yes you are correct on all counts. Except that it might be a little tough to match DVX Anamorphic footage against mini35 Squeeze footage... the aspect ratios will be compatible, but the images will look very, very different and they may not intercut too well.
I see...
The images may not intercut well because of the depth of field factor or because the mini 35 affects the picture quality in many other aspects altogether?
Both. Mini35 footage is quite a bit softer overall, and there's a really nice texture and glow that occurs on mini35 footage, that you don't get on regular DVX footage.
Although you could probably simulate the softening/glow attributes of the mini35 on your other footage. So if you're willing to work with your footage in post, you could probably get them to the point where they'd intercut pretty well.
