Hello, guys!
Thank you so much everyone for your great kind comments!
I'm very sorry for such a long time before replying, but time is a bit rough recently, and I didn't have much time to spend on the internet overall, but hope there are changes coming in that matter soon.
I've made a vid for you, guys, and everyone else who would like to see how I have installed the face inside the figure's helmet, since it is better to see once than to hear twice, right? 
Here it is:
Upgrading Moebius Viper Pilot Figure
Wow, Q! Thanks so much for the input - I was going to have some serious fight with the canopyinstallment if not this your post: I have indeed been absolutely sure that the canopy goes on the outside. Thanks a ton again!
Thanks, bro! 8)
Yes, this figure I'm using came from the Mk.II I had built for this year's contest. Since that was Starbuck's Mk.II I've used the Mk.VII's figure there as it had some certain optional physiological properties required
So the figures are switched on my Vipers builds.
Thank You, Kyp.
I have the next update coming in the matter of just several hours - only have to charge my camera to make the new pics and upload them
