EDIT:
My understanding is that the ParallelRunner is running the nodes
in parallel. It is waiting for each process to finish the 1st node
before moving onto the 2nd, etc.
Not sure if I understand this correctly but as soon as a process finishes, it will move on immediately to the next node ready to be executed. It shouldn't wait on anything.

There is an alternative along the same line of your idea about multiple projects. However, you don't need to create multiple copies of the project to achieve the same result. You can parameterise a run with a certain set of inputs and write a wrapper script (bash, python, etc.) to invoke as many kedro run
as you want. For example, if you want to have a dedicated Kedro run, which will then be on its own process, for one file in the data/01_raw
directory, you could do:
for input in data/01_raw/*
do
file=$(basename $input)
kedro run --params=input:"$file"
done
The trick to make this work is implement a before_pipeline_run
hook to dynamically add a catalog entry with the value of the input parameter. I have a demo repository here to demonstrate this technique: https://github.com/limdauto/demo-kedro-parameterised-runs -- let me know if this addresses your problem.
