In civ12 rulesets you set all units' layers to the same value.
And change this rule:

 - You cannot attack a tile if your own layer contains one or more units
but you cannot attack any of them. (Layer superiority rule.)

Exactly how it is done now, by using flags.

Layer proposal is good because it solves problems.  What problems does 
layered attack/defence strength solve?  IMO it only complicates things.
