Oracle, good idea. :) Aeronef does have some provision for ocean-going and land-based targets and such, however, you'll most likely find that the 'Nef models will work best as aerial units in standard DW rules, and work pretty well at that.
Size-wise, they should be fine. Certainly, 'Nefs aren't glaringly larger or smaller than any DW units of similar type.
As for style, well . . . The original Spartan Games models are fairly hard-edge "Realistic" designs and so are the Brigade range, so that's not a problem ( IN fact, I've been thinking of using Brigade 'nef's as the basis for scratchbuilding some vessels for my own Dystopian Wars forces ). But going forward? Here's a quote fresh from the Warcradle Studio chief today -
"I think it's important to acknowledge that visually the game is going to embrace and evolve the more outlandish concepts from second edition Dystopian Wars rather than keeping it in the ‘could happen' vibe of the first edition. So more iceberg ships and robot dragons and less WWI German battleships. Our design team, while respectful of influences and inspiration found in the real world, are much more stylistically led rather than continuing the pseudo-historical feel of what went on before. For some that means the designs are going to be going in a direction that is not for them. The ships of the Dystopian Age are not ships you would honestly expect to find in real life (with or without Stirginium), but as playing pieces in a war game we want to make sure they are visually distinctive and exciting. In that regard Dystopian Wars will have much more in common with the design philosophies behind sci-fi and fantasy games like Warmachine than historical games like Flames of War."
So take form that what you will.
