Id imagine having no differential in the rear axle will make cornering a problem and shorten tyre life considerable. Land Rover experts may correct me
here but it is not recommended driving on roads with the diffs locked - off road only.
It looks like your plans to use a Kadette as the donor are where your problems lie. That is a big car in comparison to a 200Kg bond bug replica. Id
suggest finding a far lighter donor first that could be used complete - ie something with a small light weight diff and axle. Im no expert so cant
think of one off hand - especially available in your part of europe.
What about front wheel drive??

The land rover thing is the centre diff, if you lock that you really are trying to tie the treansmission in knots.
On a very light car a locked rear diff is not such an issue (will still be very "different" to drive though)
I would recommend the first drawing, with chain drive to a solid axle, but use a motorbike engine of some sort.
Retro RWD is the way forward...........automotive fabrication, car restoration, sheetmetal work, engine conversion
retro car restoration and tuning

gearshift is very easy for the bike engine, just has to push and pull.
If you get an engine it will be very easy to see how to do it.
The kadett gearbox is harder to do than the bike one for this.

why not use the old fiat 126 as a donor, was sold on to FSO ans remained in production for some time after fiat stopped making it.
Low on power, but you are planning a light weight car lighter than the donor.
rear engine, light weight, front suspension could be used. pukker

You connect a linkage from the original gear pedal to a lever next to your seat, or you could use a set of paddles mounted behind the steering wheel
like modern WRC rally cars.

Just have a look at the many bike engine cars on here for inspiration, you just connect the shift rod to a lever instead of a pedal.

Why would you want to lay the engine down? 
You just need to make up a lever to fit where the normal foot operated one is (easiest to modify the existing lever), which allows you to connect to
the gear shifter next to you via a rigid link. You dont need a spring either. About the most simple gear shift mechanism there is....

This has to be one of the most simple gear linkages possible, if you are struggling at this stage, then maybe you should consider starting a simple
project to begin with. You will face much bigger challenges than the gear linkage in a project like this.
The linkage will be simmilar to how it is shown in your picture, but there is no need for a spring, and certainly no need to mount the engine at a
different angle. Note that you don't have to keep the gear change pedal in a horizontal position, the pedal on most bikes is on a splined
shaft, you you can take it off and replace it at a different angle to make the linkage simpler. Even if it isn't splied, you would simply cut
and weld the lever so it points in the direction you require.
