You could probably convert that D into an E but youre in for a lot of work.
That hump on the dorsal section of the D is the in-flight refueling receptacle found only in Air Force variants. The E had the Navy retractable refueling probe on the starboard side of the nose. To convert your kit, you will have to remove the hump.
The E used the SJU-8/A ejection seat while the D was equipped with ESCAPAC. The E and the D also used different main wheels. But I guess in 72nd scale these details can be overlooked.
The E also had a catapult tow bar and approach lights attached to the nose landing gear. This is absent in the D. This, pehaps, along with the retractable probe, will give your kit an "E" flavor.
The antennas you see on the tail are ILS antennas not present on E models.
Hope this helps.
