Replace GMod Physgun with HL2 Supercharged Physcannon [Model]

[Yonice]

Hey folks, since I am not capable of doing it on my own because my knowledge about this is pretty low I am asking you, if you could create/modify the HL2 Supercharged Physcannon or Zero-Point Dark Energy Field Manipulator or whatever you would call it (the physgun that lets you push/pull ragdolls/npcs) to work in Garrys Mod.
What I mean by that is not being able to use its features, but instead have its animation. Look at the gifs provided and you'll understand what I mean.

Theres also the command "physcannon_mega_enabled 1 " which lets you get the supercharged one in HL2 but it doesn't work in GMod. (Again, I just want the animations)

So can anyone create a physgun model which uses the HL2 Supercharged Physcannon animations?
And if possible also replace the Attack animation with the AltAttack animation from HL2.

If you don't know how or don't want to can you atleast help by figuring out why it doesnt play these animations in GMod even though it uses the exact same model? Thanks.

That's not animation. The lasers, sparks, lightning and glow are all done in code, which cannot be changed in GMod.

So the behaviour of the model is hardcoded into GMod and cannot be changed? Aw..

You can make a physgun-weapon. A copy of the real hl2 big physgun? You can also make pistols.
