While I know some people don't like applied radio filters on voice mods, it's purpose here is two-fold. The first reason is obviously to make it sound like it's coming through a radio transmitter for increased immersion. The second reason is a bit more ???. David Hayters voice direction throughout these games is a bit varied, his performance in Smash is extremely gravely and sounds close to old Snake, probably because it was recorded around the time of MGS4, but the portrayel is still supposed to be young Solid Snake. Twin Snakes has some gravel to the voice, but not on the level of Smash. MGS2 and Bomberman Snake has pretty much no gravel to the voice. The purpose of the filter is to blend all the voices together and make the performance disparities less noticeable. It's still somewhat noticeable if you're paying close attention, but the line diversity and quantity matters more for this mod than the consistency.

As you're probably well aware, Twin Snakes is just a remake of MGS1, so most of its line contributions are just alternate versions of lines from MGS1.

Using R.A.G.E. strike will sometimes make him Falcon Punch. It's guaranteed if you use the previously mentioned variant.

Snake will sometimes break into short bursts of tutorial exposition courtesy of the plethora of MGS2 dialogue.

Known issue:
Some of Snakes line are louder than others. This is most apparent with his Bomberman lines and his non-codec Smash lines. This is because the different games seem to have mixed the lines differently. When applying the radio filter, I normalized all the lines in bulk to get them all to a semi-similiar amplitude, but there is still some disparity. And because of the way that the normalization works, the longer a line is, the lower volume it ends up being. Even if I knew enough about sound editing to fix this, it would still involve re-importing all the lines into another upk package and remaking all the cues and archetype from scratch, which I REALLY don't feel like doing. It shouldn't matter too much anyway, as long as your SFX isn't blaring over all the voices, you should still be able to hear what he's saying. And of course, you can adjust the volume of the pack yourself in the config. I may put all the lines I used into a publicaly available cloud folder if people want.
