By definition, the secondary flow is going to be a fraction of primary flow... the difference will come from flashing in the separator. The question is not will it work, but rather how well will it work?

In this industry they do not use the terms primary and secondary, for that reason, "motive and suction" flow

How do we prove if it works? Then How can we make work?

I think you have with your drawing & the posts (unless I am missing something)

Your controlling condensor pressure

Your removing flash gas, improving mass to txv, improving evap efficiency

Your increasing suction pressure

Overall refrigeration efficiency has to go up ??? Surely

Now I can see it - I can not see any pitfalls (anyone agree ????)

The pic is just a snapshot in time at a steady condition!
Practically and what is required to prove performance is a the system moving to reach a steady state.
The compressor inlet pressure will only increase when the process is underway, so to start with it will run similar to a normal system, as we start to recompressor, the compressor mass flow will increase, which inturn makes more flash gas in the vessel, which gives greater levels of recompression and so on until equalbrium is reached.
