I am a bit sceptical to change naming this way. This will also often bring name collisions. Every MRI of a single patient will be named equaly!!!
I think this will drive a lot of users mad, escpecially because it is more likely that they have a multi-modal/multi-parametric scenario then a multi-subject scenario in the workbench.

I definetly would keep at least the series desciption or use all 4.

I think at the end (but not as a hard requirement) it would be best, that we allow the configuration of the node naming patterns. E.g. a mircoservice were you can register for different data types which name template and property keys should be used to generate a concrete name.
