Interesting note: Kawamori Shoji works out the functional aspects of a design often using Lego blocks. A major one was the transforming and combining design of Aquarion.
He worked with Lego for the 2006-2008 Exo-Force series, and made some "unofficial" models available at conventions titled under the "VAN-Force" series. Since Shoji Kawamori held the copyright to the "unofficial" designs, Lego couldn't release their own instructions.
Fully Transformable, with little to no parts-forming.

You can really see the Valkyrie influence with the first two links.
He also really likes making Valkyries out of Lego blocks.
By the way, if anyone can get a scan or pic of the instructions for those sets, I would GREATLY appreciate it.
Especially high res scans of Figure Oh vol 95 and 96.
