The OP's hitch would be impractical because number one, the Timber Hitch +Half hitch works very well .
Any bend is impractical because the Zeppelin bend works very well. Any woman is ugly because there is/was Monica Bellucci.
The timber hitch is the less clever hitch I know - and the series of the half hitches is the second one ! I guess that their combination can not go much further... It works very well, but what does this mean for every other hitch ? It may have been used "in the wild" by professionals at one or more points in space and time, but what does it mean for the knot itself ?
It means that unless you can come up with something
"less clever" --which seems to mean "simply effected"--
to compete with this structure, don't make any noise.
Which is why the
zeppelin bend is sitting idle so much,
as various "less clever" solutions meet the needs.
(Still, there are some who believe that they have
reached the absolute end of the knotting alphabet
with the Z --or its Z-enith.
)
The OP hitch tries to explore a clever idea :
to secure a bight under some riding turns,
and then pass the standing part through this bight.
It is the same idea used by fishermen when they tie their hooks, and it is called "snell-ing" ( the Snell knot, in its many variations ).
Well, it's unlike any effective snelling I've seen,
as the SPart here will pry out the wrapped bight
--it's backwards, in effect.
As for fence-post extraction, an concern might be that
pulling up from one side could be improved upon by
having a two-sided hoist, something akin to the old
barrel hitch (which in one form is an
overhand knotopened to have a barrel inserted down through its
"spine" onto its "belly". Especially for pulling up some
smooth, metal posts, some sort of increased wrapping
as shown here might be necessary.
