Also I'm struggling to think who would want to place him on the throne or how it would be accepted by literally anyone. b*****ds don't normally have right of succession unless they take it by force or are legitimised by their fathers I think. You would think a b*****d or usurper would have to have either force, the backing of noble families, a noble upbringing themselves or all three. Gendry has none of that and a tenuous claim by succession law doesn't help him at all.
