Bleh, no. Lets stop this drive for "Whatever is added has to dominate what we already have" attitude.
HiTech's comment reported in the Do335 thread already leaves the F7F, F8F, He162, Ki-102, Meteor Mk III (already known due to the last poll), Spitfire F.21 and Tempest Mk VI as options.
The other problem with many 1946/47 planes is that flight data is not available for a wide selection of them. The J7W1, as an example, looks really interesting, but who knows how it would have performed as it only ever did its initial, gear down, test flights.
