I can see the energy shield upgrade tech basically giving way to Sam's "hardlight wings" in the mcu
The artist discussed how he was “looking for a way to minimally add an element to the shield,” one which would “hint at the Wakandan upgrades before you see them used:”
"Ryan [Meinerding] asked some of the [Visual Development] department to take a little bit of time and think up some new ways that Sam could use the shield, more specific to him and his own physicality with it… when I was thinking about the tech rim piece, I was looking for a way to minimally add an element to the shield so as not to distract too much from the shield itself but still make it feel like it could have a believable tech addition and hint at the Wakandan upgrades before you see them used.”
Captain America, Sam Wilson
Black Panther, Infinity War, Wakanda Marvel
One version of this “Wakandan shield tech add-on” included “rim pieces shoot[ing] outwards and fill[ing] in to make a larger energy protective barrier.” The cherry on top? This energy would have the “Falcon wing motif in [its] design.”
