One problem with a new parallel strip is that all ops are going to have to cross 27L/09R - so there will be delays.
That is not correct. T6 and R3 will operate virtually as a stand alone airport. The only traffic from T6 that must use one of the main runways for departure will be Dovers. This is estimated to be about 4 per hour. Traffic from the other terminals will operate as they currently do.
Edited to add; plus any types (340!) that cannot accept 2,200m.
