Golden Eclipse (Nerf Stampede Mod)

Here is my finished modified nerf stampede.

All the parts that were yellow on the guns was painted gold, and almost all of the rest was painted black. 

If you didn't see my earlier photos of this, then I will tell you what I have done.
I fully modified a nerf maverick to the best of my potential, cut a part of the stampede off, and part of the handle off of the maverick and glued the maverick onto the under barrel of the stampede. It is basically a stampede/ maverick integration.
No modifications had been done to the stampede until I had painted it, but since then I have upped the voltage to the motor in the stampede by soldering on a battery pack that holds 8 AA batteries. This makes the gun shoot about 4 shots per second. This also made the gun quite lighter, and more balanced all together. With the 6 D cell batteries in the back the gun was really back heavy; but now with the modified battery pack the gun is lighter and shoots faster. Overall I think this is the best nerf gun modification I have ever done.
Please leave me some feedback. Is this a good idea at all?
Also, I would like to know how I could put the name of the gun (Golden Eclipse) onto the stampede somehow?
