Who knows how to make this? should be not very compex

I want to edit the Cluster Rockets' missile model, replace the rocket with the skull head in Death Coil's missile, and add a long long tail to it.
Is it possible? Thank you:)

Theoretically, yes. You'd need to extract the skull geoset from the death coil, merge it onto the missile, move it into position, and then edit the ribbon emitter to leave a longer trail. Oinkerwinkle's website has a tutorial on geomerging with his tools, and Magos' Model Editor is your best bet for editing the ribbons.

I can't visit Magos's website could you please mail Model Editor to me?
