^^^But, looking at the parts, and listening to those fellows on the R2 video, it seems as though they had Scout/Destroyer conversions in mind when planning things out. The Nacelles are designed with 90 degree rotation in mind and the lower end of the interconnecting dorsal seems well suited attaching to a nacelle... the possibilities are certainly evident...
Also, I didn't know Alex Ross did the art. That's Awesome! The man's a genius! Marvels
and Kingdom Come
are two of my very favorite comics!
