I wonder if intercept rules by themselves would be enough to make flanking workable.
Basically intercept from 13th Age means that you can move to intercept and engage someone who tries to get past you. If adding this to grid based 5e I would make this a special action* that can allow you to move up to half your speed in response to someone elses movement.
This would make getting flanking something that's more difficult to get - as if there's another enemy nearer than you, they can move to block your flanking or engage you before you get there. If you did this and just made flanking the traditional +2 it may work better.
*My first thought was that this should be reaction - but that doesn't work because you have already used your reaction to engage, so the threat of engagement would be toothless (this sort of thing is a common issue with 5E's action economy).
