How would one custom-make a Mega Bloks Z with body?

[LuckyLadybug]

So for a long time I've been wondering what I might be able to do to make a Mega Bloks figure of Baxter's alien computer friend Z, as depicted more or less in Son of Return of the Fly II when he had an energy-generated body. I have a Mega Bloks computer, but am puzzling over how to go about making the body. One thought would be taking a Foot Soldier and painting it blue and then trying to attach the computer, but I don't even know how I would do the attaching satisfactorily. My experiences with glue, even glue that's supposed to work on plastic, have been sub-par and things just tend to break. I'd want it strong enough that I could make photoshoots and, well, even play gently with the figure without things breaking.

Also wondered how hard it would be to mold a semi-transparent body from scratch, but that is likely not an option for me. And I don't imagine Mega Bloks has ever released any figure from any line that's already transparent blue....
