First the superfunction is not unique but computing what a function is the superfunction of , is almost unique ; just a single parameter usually.
If we have a function f(x,y) that is analytic in x and y and we take the superfunction F(z,x,y) (with the same method) WITH respect to x , for every fixed y , where z is the number of iterations of f(x,y) ( with respect to x ) then F(z,x,y) is usually analytic in both x and y !
Therefore the superfunction operator is an analytic operator.
this makes going from x <s> y to x <s+1> y - for sufficiently large s - preserve analyticity.
Secondly we want
x <s> 1 = x for all s.
by doing that we set going from x <s> y to x <s+1> y as a superfunction operator.
This gives us an opportunity to get analytic hyperoperators.
Combining x <s> 1 = x , the superfunction method going from x <s> y to x <s+1> y and the left distributive property to go from going from x <s> y to x <s-1> y we then get a nice structure for hyperoperators that connects to the ideas of iterations and superfunctions.
You see we then get that x <s> y is EXACTLY the y th iterate of x < s-1> y with respect to x and starting value y. If we set y = 1 then x <s> 1 = x thereby proving that it is indeed taking superfunctions *we start with x * (for all s).
This implies that
x <0> y = x + y is WRONG.
We get by the above :
x < 0 > y = x + y - 1
( x <0> 1 = x !! )
x < 1 > y = x y
( the super of +x + 1 - 1 aka +x y times )
x < 2 > y = x^y
( the super of x y ; taking x * ... y times )
x < 3 > y = x^^ y
( starting at x and repeating x^... )
This also allows us to compute x < n > y for any n , even negative.
That is a sketch of my idea.
Not sure how this relates to 2 < s > 2 = 4 ...
Now we only need to understand x < s > y for s between 0 and 1 but analytic at 0 and 1.
Gotta run.

However this idea has issues as well. And with " as well " I mean to express my skepticism against all known hyperoperators.
A typical issue in fact :
let <-s> denote negative hyperoperators
from the above 3 conditions above we get
x <-s> y = y + 1
well at least for integer s > 0.
This is ofcourse problematic considering the superfunction operator.
And the loss of info for the x parameter.
We cannot simply say without " shame " that the *super* of x <-2> y = x <-1> y = y + 1 and the next super is not that fixed point function but x + y - 1.
It is also weird to think about functions x <-1.5> y between y + 1 and well y +1 ?!
Almost every hyperoperator proposed for generalization has similar issues :
for negative orders the equations are undefined , inconsistant ( log (0) or oo or inconsistant ( nonunique ) values ) or we end up with identity or successor functions.
For me that is not a small issue.
The problem runs deep , i mean for almost every linear function occurence this issue arises.
And to fix the issue we could try stuff like x <1> y = x^2 + y^2 + 1 but this is not really what we want is it ??
We could also try stuff like x<s>y = a* ( x <s-1> ( x<s>(y-1)) ) + b * ( ( x<s>(y-1)) <s-1> x ) with a + b = 1.
But that also does not seem what we want , lacks nice solutions and has similar problems ...
So we are not stuck but super stuck.
(ok that is a bit of a joke )
