I personally hate Combustion, but it fits in the theme here.

I would take Neutrino Bolt instead of X-Ray Beam.

Other than that it looks okay.

Here is where I would go with your idea. Slot IO sets for +end and +recovery. I like to get max HPs and high regen as well, although +defense is very useful too.
