Certain figures due to their overall design will have limits on their range of motion such as older lines of figures pre-2000s or bulky figures. Marvel legends are okay for overall range of movement and posing, but aren’t the best out there if you want precise and subtle movements of parts to make more fluid motion (many ML have ratchet-like movement in knees and elbows). Same for similar-engineered lines. Figma, Figuarts, more modern Revoltechs, mafex, and even some more recent Necas have smoother joint movement for that. Although bear in mind that sculpted clothing like skirts, capes, etc won’t afford as much movement and can look odd if it’s stiff plastic (looking at you, Figuarts TFA Kylo Ren). Soft goods can mitigate this issue at the cost of not looking like cloth would at that scale (think what your clothing would look and move like if it was stiff burlap).
Making figures through kitbashing existing ‘blank’ bodies and character heads with softgoods clothing is what the Robot Chicken guys did most of the time, so you could grab Body-Chan/Kun, Sozai-Chan/Kun, Archetype She/He Next, AZone, Romankey, and others more to accomplish that (and just reuse bodies to save on number of figures to be bought.
Hope that helps.
