Very cool wish!
Yes, that would be great.
Currently for all sorts of repeating Displacement-Patterns with smooth gradients (16Bit) one needs to use Photoshop to create them.
While Photoshop is pretty poor with Vector-Creation it afaik the only App which converts Vectors to 16 Bit Images.
If Maxwell would read Vectors from all sorts of Packages in formats like .ai or .svg the creation of repeating high quality maps was a lot easier,
especially as in Illustrator CS6 they finally established an
interactive way to define patterns.
Maps could easily get changed and showed updated in Fire.
