No.

The very idea of 'syncing clocks' by means of light rays, is -in my 
eyes- nonsense.

I simply assume a (hypothetical) signal of infinite velocity, that would 
connect without delay.

This does not exist, but that would hinder its use to define simultaneity:

Two events are simultaneous, is such a signal would transport the 
information from one event to the other.


Light is slower than that, so this would exclude light from the 
definition of simultaneity.

Therefore I try to remove the 'other clock' from the picture and define 
time by the initial observer alone and make his clock 'universal' (for 
himself).

This is apparently how the universe works and we have in fact such 
'universes', each equipped with its own time.

'Anisotropie' means something like 'not always the same'.

Yes, that's actually possible. But it takes a device to measure such an 
anisotropy (of one ways speed of light), hence a measurement of OWLS is 
required.

The apparatus I have suggested is in principle capable to perform such 
measurements (of anisotropy) , since it could be mounted on a train, 
plane or rocket. It could also be moved, tilted, accelerated or filled 
with different gases.

That's all possible, hence I would like to see such a device being built.
