>whether the wings could be their own separate thing or if they needed to be part of the arms for true powered flight.
That is not even a question. There ISNT a question like that - it HAS to be a wyvern/bat like design, no
exceptions. The body will be tad shorter with more defined chest (kilt is a hard requirement, it will be base skeleton-mechanism for the massive chest muscles).

The wings area probably will have to be bigger than the bats one though, but not by much
