Me?
Iid use a plate type undertray with some holes near the front and some various areas underneath, an open undertray allows ponted rocks in to hole the sump, seen it happen
Tray under the tank and a layer of foam to stop stones from getting in which could cause a hole if the back takes a big impact
A plate between the rear bumper brackets and kicked up to protect the seam along the light panel
Id weld some small plates to the underside of the arm by cutting up an old arm the arms usually fail just inside the weld that holds the swivel hub eye
id fit rock sliders a piece of alloy angle on the shocker pins and fitted instead of the large spacer washers ( but countersink the holes as on the washer)
id fit rear knife edges to the front they are bigger and stronger( and then you wont need 2 types as spares)
id fit a battery support and strengthen the area around the wing bolts on the bulkhead
id disable the steering lock fit a push button start and move the fuse box and the relays to the inside of the cab
id fit poly carb or "lexan" windows all round and make sure the screen was a laminated one ( single biggest weight saving you can do!)
id just take Toyos( my favourite but any other 135 would be fine) as most of the driving is going to be on dirt roads and from my experience even African dirt roads are better than the metalled roads found in most of the UK. Tread pattern and compound are irrelevant on gravel and dirt remember its not going to be like some "Trials" course where you have relatively short but extreme difficulties or a "Rally" where you have to drive so fast your close to the edge of control. If the roads that bad get out and plan the route. Id also not fit a roll cage Id just drive sensibly ive never had a 2cv ( or any other car) fall over. stupidly big or chunky tyres just make it noisy. Michelins are just too fragile with really vulnerable sidewalls avoid fitting tubes as they guarantee punctures and blow outs - have a couple as emergency.
some extra accessory sockets for sat nav phone charger etc
a big metal box bolted down to the rear seatbelt mounts and lockable - big enough to take a laptop camera etc
id do as much stopping and chatting to locals as is possible take pens and little notepads for kids ( and some wrapped hard candy sweets) and some minatures of whisky - local police LOVE their whisky ( especially the Muslim ones " there is nothing in the Koran about whisky - wine yes, whisky thats differednt!") people are the same the world over it seems to be the WASPS that are the ones most prone to random acts of violence.
and have some fun doing it dont go looking for dangerous stuff for the sake of Adventure ...." if you want adventure - run out of petrol!"( some famous adventurer or other)
as with oil and ignition ...you'll find I'm right ( unless someone is righter)
