P.252.02 was a large aircraft.
You can see large static radiator three side view in bottom original drawing.

This drawing shows P.252.01? Very similar to P.252.03.
Source : LUFTWAFFE SECRET PROJECTS GROUND ATTACK & SPECIAL PURPOSE AIRCRAFT, ISBN 1-85780-150-4

You can see radiator arrangement of this design from this drawing very clearly.
The relation between P.252.01, 02 and 03 are very complicated!? ???
Bottom picture shows P.252.01 night fighter version. This was a two seat fighter. Front engine was located just behind the cockpit.
Some document says that P.252.03 front engine was located just behind the cockpit,too.
Various document says as follows.
P.252.01 ; Span : 16.4m, Length : 15.2m, Height : 4.95m, Wing area : 43 square meter, Wing leading edge sweep back angle : 25°
(Some document says that P.252.01 had a straight wing)
P.252.02 ; Span : 18.4m, Length : 15.0m               Wing leading edge sweep back angle : 35°
P.252.03 ; Span : 15.8m, Length : 17.2m, Height : 5.05m Wing area : 50 square meter, Wing leading edge sweep back angle : 25° or 22.5°

Following version existed?
P.252.01 ; Two seat fighter bomber, Zerstörer, Two seat night fighter
P.252.02 ; Two seat Zerstörer(Destroyer), Three seat high altitude night fighter
P.252.03 ; Three seat night fighter

You can see common air intake for front engine ram air intake and radiator air intake in the top drawing.
This arrangement secure some air flow into the radiator at zero/low speed?

I checked the plan view of the "works drawing" you supplied. Its length vs. width aren't even close to the numbers you've quoted for the P.252.01, but they are exactly right for the P.252.03. Also, it's clearly a three-seater with a radar dish. So either the drawing shows the -3, or the designations have been mixed up, or... aliens ;)
