Most likely he would get the power of everyone he scans. It’s like upchuck, the perks and murks only difference is their appearance yet that makes the genetically different enough for both types to be stored. So when bringing up quirks the same logic shouldn’t be such a stretch since even though they are humans their powers differs quite a lot meaning that different people with their own quirks could count as their own sub species. But it is unclear if people with similar quirks like Tsuyu family (who all have a type of frog quirks) would only need one member to be scanned to receive a form or would all be scanned cause of some minuscule reason.

No, not possible
