Inverse Branching

I do an example to explane better my idea.

Hypothesize to have a list of 5 curves:

3 with similar lenght (1,2451 1,2448 1,2452)

2 with similar lenght (2,4431 2,4428)

The curves are disposed in a flat data structure.
The goal is to create a branch structure with 2 paths with curves of similar lenght
For example, with a function command with a round operator we can equalize similar data, but when we do that the GH doesn't recognize equal data to sort that data as branches.

Do you think is it possible with the actual GH version?

If it is not possible, I give the question to David: do you think it would be good (and possible) to create a command that recognize similar or equal data, or an into command automatic branching creation button when we have similar or equal data?

It is a sort of "inverse branching".

Thank you,
