Leclerc has been used as a platform to test a 140mm gun:

IAV 2019: Nexter tests 140 mm gun on Leclerc MBT

Nexter has fit a 140 mm gun on a Leclerc main battle tank (MBT) to gather data for the Franco-German Main Ground Combat System (MGCS) programme to replace it and the Leopard 2, Jane's learned at the International Armoured Vehicles (IAV) 2019 conference held in London on 21-24 January.

This is understood to be the first time that a 140 mm gun has been successfully integrated onto a 50-tonne MBT and conducted over 200 firings. It is expected to provide a 70% increase in firepower over a NATO standard 120 mm gun.

Nexter has resurrected past efforts to develop a 140 mm main weapon to establish which firepower solutions are best suited to meet the MGCS requirement.

Probably the old one.

Though AFAIK while the gun was tested on it's own, integrated to a turret to test the new autoloader, it has never been tested in a complete tank.

So my guess is that the purpose of those test is to determine if a 140mm is much harder to integrate than a 130mm and if it would be interesting to makes provision for it.

They probably already have all the ballistic data needed (unless they are testing new 140mm ammo).

Apart from the confirmation that the 140mm trials where to asses the capability to integrate a 140mm in a 50t tank, it was announced that at IDEX 2019, they'll present a Leclerc with a drone attached which main purpose would be reconnaissance and target designation.

 

Qualification of a new programmable HE round called M3M (Impact, delay, airburst) will begin shortly.

Nexter is also working on yet another APFSDS called SHARD (probable that it will never see service like it's predecessors) and apparently the Polynege guided ammunition is still on the table (which would work well with the new reconnaissance UAV)

They were the entry in competition with the AMX design for the ELC project:

AMX Leclerc Series 1 Special Armor distribution in the hull and turret (not including the spaced heavy side skirts). Once the model is complete i will use it to do some vulnerability modelling along the lines the data presented in the Swedish Tank Trial diagrams:

Your front hull cavities aren't deep enough.

I used this image to get the lower boundary of the center hull cavities. For the the cavity thickness I used a prototype Leclerc diagram as a reference and two images of the Leclerc front hull under contruction. Using the two images I got a rough ballpark range  of around 590-690 mm using CAD and photomatching techniques. With the prototype diagram i got a thickness of about 620 mm. It seemed like a plausible number so I went with it.

I can provide some more detailed explanation including the sources if someone wants to know. I was very careful in my evaluation.

 

I will use this model to create a vulnerability map:

I was referring to your vision of the height of the special armor cavity. In your drawings, it stops at the heigh of the welding seam between the top and the lower front hull plates.

What weldline are you referring to?  At the weldline B the bays might be a tiny bit deeper but I do not think it will be more than 30-40 mm.

IIRC there was video with tank production where you can see all cavites 

I used this image as a reference as well. Sadly,  I have not found the original video.
