Well, higher muzzle velocity and greater rate of fire would be pluses. Of course, after you ran out of shells, it would be a tad useless. Also, the fire control systems of the time couldn't deal with the fuze setting or velocity measurement systems that are included in may applications of the 35 mm.
So it would be better to make it human operated then? Probably would be better to make it fire roughly 400 rounds and not 550. That number seems to high for me. Could better converse ammo.
When did fire control systems know to deal with fuze settings and velocity measurement?

Pointing at the incoming plane under radar fire control is easy. It's also not likely to hit unless the plane is heading straight at you or is very close. Combining radar fire control and lead-computing (developed late war for fighter gun aiming/firing), however, could do the job.Why isn't it enough for the auto cannons fire control to anticipate where to shoot the plane? Like find that it gets in range and shoot at it? Kinda like a early version of the Phalanx CIWS.
Was the technology in world War two there to allow CIWS weapon systems on ships or no?
...fare as anti-aircraft artillery in the Second World War? Would it prove to be superior to the 40mm Bofors of that time period?
I am aware that it is powered by fire control radar and not by human gunners. So just use whatever fire control radar they had in the Second World War. Even late war fire control radars if you wish.

No, at least in the modern sense. It took dozens of individual 20mm cannon for instance to form a CIWS system on a WW II ship. When the Kamikazes showed up the black humor was that when the 20mm guns opened fire it was time to hit the deck (prepare for impact) for the other sailors.
The ability to predict the future flight path of an airplane or Kamikaze with a high degree of accuracy did not exist.

The 40mm Bofors in the US Navy often used the MK 51 director in the lower left part of the picture.
The MK 51 weighed 710lbs above deck.
The MK 52 was a modified MK 51 carrying Mk 26 range-only radar. However this boosted the weight to 1710lbs above deck and 1320lbs below deck, WW II electronics was neither compact or light.
These directors were used post war for the 3in AA guns.
Operating limits for the Mk 52 according to one source was lead angle 20 degrees, target speed 350kts, range for surface fire 12,000yds, for AA fire 7,000 yrds (this limits sound like they are for the 3in gun.)
The MK 63 was a MK 51 with tracking radar mounted on the gun mount.

Weights went between 3900lbs and 5400lbs.
Detection range is given as 37,000yds.
Tracking range is given as 35,000yds.
Computing range is given as 7,000yds.
The above decks director pedestal weighed 1300lbs.

The USN was thinking about a "free-swinging" 35mm gun shortly post-WW2. It never came to fruition, possibly as a) it wasn't likely to be as good as the 40 mm Bofors b) the 40 mm Bofors was found to be insufficient against kamikazes and was expected to be insufficient against guided weapons (which were in the USN inventory by this time), and c) proximity fuzes.
While a modern 35 mm, like the GDF or the Millennium (especially the Millennium) may be quite effective against WW2 aircraft, their effectiveness depends a lot on modern fire control systems, which couldn't be built before the 1980s, at the earliest. While a Millennium with AHEAD or a 40 mm with 3P ammunition would do quite a lot of damage to incoming aircraft, they'd do far less with 1940s fire control systems and the sort of ammunition that could be made during WW2.
