If she really EE then there is no sense in mention BFR, just say EE, because if you already EE something then there is no battle logic (or any logic in general) in recreate said thing in a different realm,
@Vietthai96 said that the EE is done because the place to which she teleport something have a EE effect, so the BFR isn't done by a 11-D EE so isn't a 11-D BFR potency (because that don't even exist), and he also said that she don't do that in the opponent in character so isn't something to consider, compared to that is more probable that Romulus become her Roma at the beginning because he like to do that.
