These are some interesting finds
however there is one flaw with these lab works that I must point out…
Unless we’re talking about a reversal which has no strike-invulnerability, then we cannot theoretically make any sense of something being meaty+counter-hit
Counter Hit = A normal hitting the opponent during the startup of a normal/special move.
Meaty Hit… = the scenario in which normal/special’s active frames are present during the rising of the opponent at such a timing that the opponent’s first ‘recovered’ frame is IN the hitbox of the attacking normal…
From the definitions we can see that these two can virtually never exist simultaneously.
A counter hit requires the opponent to be able to push a button of some sort to get counter hitted!
A meaty hit presupposes ZERO frames in which the opponent has, not even the chance! to hit a button!
so the question is: if a normal is meaty, there how can it at the same time counter hit? if the opponent doesn’t have the time to hit a button, then what is the meaty normal counter-hitting???
If the opponent has no time to make the mistake of hitting a button, there there is no normal or special move in which we can COUNTER-HIT!
This is a a little theoretically dense maybe I understand, but all I’m trying to point out is that the viability of your lab work/findings is going to depend on the existence of a frame window gap between the final normal connected and the counterhitting normal,
So… unless I’m mistaken so far in my reasoning, the conclusion is this…
The far fierce either has to be meaty or counter-hit, it cannot be both!!!
Far Fierce + 2 on hit,
counter hit = +5
don’t know if anything interesting can be done with this
Far Fierce has 3 active frames and thus can potentially be +4 best meaty scenario
don’t know if anything interesting can be done with this.
One final thought
I truly do hope that I’m wrong about this in some way and that your lab works turn out to be viable. A use for far fierce in a mix-up game would be very sweet indeed 
However if it turns out that for some reason known or unknown that this tech doesn’t turn out viable
it was somewhat doomed from the start.
For far fierce to link into step kick, not only does it need to be both meaty and counter-hit, but from there it would be a one frame link into step kick 
Requirements like that that ALONE are enough to strike a killing blow to any piece of tech.
