The humble box-nought

[The Lost Son]

So between a few topics on the boards and a few too many sleepless nights with a teething baby my thoughts have been returning to the greatest of dreadnoughts the castra ferrum. 

The big one that started this is @Grotsmasha's brilliant upscaled grey knights and the fact that the new Saturnine termies are more or less the same size as a venerable dread.

Now to get to my actual point, I'd love to see a rescale of the old box, I'd assume it would realistically be under the umbrella of the heresy given 40k's new love for the redemptor chassis but how big should it actually be? The original fluff had them created for zone mortalis operations, tight confines of cities, space hulk's and the like so would a slight leg extension be all it needs in height (obviously a big upgrade to detailing etc or just remake the forge world mk4s)

Another tangient thought from this is imperial architecture must have some excessive internal volume and structural strength seen as space marines never seem to have trouble moving around. But that's a whole different thing, any thoughts would be very welcome

I think a slight increase to the same height as a Contemptor, or between Contemptor and Leviathan would feel right.

Yeah when they first made the contemptor in resin I remember thinking this is how big a Dreadnought should be, that and the legs making sense.at that size it would read well with both scales as well
