Convoluted is probably the wrong word to use.
More complicated is probably a less harsh and better way to say it.
I don’t see the real need for increased consolidation ranges, so you are bouncing off a brick wall on it.
What I specifically don’t like about your proposal though is that you are measuring one fighters movement off another independent fighter, which isn’t something that happens anywhere else in the rules.
Would you also allow a fighter to shoot an enemy in combat by measuring to their friendly fighter that is closer?
Would you allow a fighter to charge an enemy fighter by getting into base to base with a friendly fighter who is already engaged?
Both of those examples use a similar idea of measuring to/from both engaged fighters, but neither feel very “right” because they involve measuring to the “wrong” fighter.
I do appreciate the issue you are trying to solve, I just think it is just as effective and simpler to just change the consolidation distance itself rather than the point of measurement.
