Was thinking like, hyperextending leg actuators, reverse jointed legs, and talon-like feet for usage in melee combat. I plan to make a highly melee focused build.

Yeah, those work fine, especially for a Raptor chassis. Most Juggernauts we've drawn in early art are built upon a swivelling hip, so they can turn a full 360° irrespective of their legs' cardinality.

Oh so I can just... Design my own weapons, throw them at you, and see if they fit?

If they're like, markedly different than any of the defaults then sure. If it's "close enough" in size and concept to a pre-existing weapon card then i'll just say you can use the stats of that card for the purpose of your sheet and then you can flavour it however you wish. But if it's just something I never got around to making and you have an idea for it, pitch it to me and we'll work something out.

Again - tell me what you have in mind and we can go from there
