It sounds like very poor typography, but I am simply looking to shift a wrapfig picture up, but in particular so it would ever so slightly go above the start of the paragraph and into the subsection line. See the attached picture below.

I provide an MWE for the picture and surrounding text (I have simply copied a load of bits from my preamble of my larger document! Apologies for the useless parts in there!).
I expect nothing in my preamble will interrupt this. I have tried putting vspace in both the wrap figure, the tikzpicture and before the entire figure in braces. Even with the abnormal vspace-25cm, it seems to only take the picture up to the very start of the paragraph and section - I want to slightly break this bounding box. Any suggestions would be welcomed.

The easiest to move a wrapfig up is to change intextsep, as it is used also at the bottom, you must insert a rule there to compensate. The drawback is that it moves the text at the side down. One can use vspace-2cm there to compensate.

We have described the spinor-helicity formalism as a natural way to encode massless scattering amplitudes. However, we have to impose momentum conservation by hand, since spinor-helicity is derived from a Lorentz invariant foundation, which can be thought of as a subgroup of Poincar'e invariance. The 10-dimensional Poincar'e group includes translations (3 spatial and 1 time) as well as the 6-dimensional Lorentz group, consisting of 3 boosts and 3 rotations. Hence, spinor variables are not invariant under spatial translations, and momentum is not automatically conserved footnotemark.
Since all scattering processes naturally conserve momentum, we would like to have a formalism where both the on-shell massless condition, $p^2 =0$ and momentum conservation, $sum p^mu = 0$ are manifest. This comes in the form of momentum twistors, developed by Hodges as an extension of Penrose's twistor geometry.

footnotetextThis is a well-known consequence of Noether's Theorem. See REFS REMOVED For more explicit details.

We take inspiration by considering a different geometrical interpretation of momentum conservation. We start by drawing an $n$-sided polygon in dual space, as shown by Figure reffig:Diagram_Mom_Con.
There are two ways to consider defining the polygon; either through the edges or the vertices. Considering the edges, we obtain the traditional statement of momentum conservation; the $n$ edges form a closed contour, which corresponds to the net sum of momenta equalling zero, and no new intuition has been obtained.
par
Let us now define the polygon through the vertices, using a new set of dual coordinates $x_i$ where $i= 1,dots,n$. To ensure our contour is closed, we demand the periodic boundary $x_0 equiv x_n$. The momenta in dual space may now be defined as the difference of these dual coordinates

Another possiblity is to use a raisebox and to hide the height from the wrapfig. You must then also set the baseline of the tikzpicture to the north.

The conceivably easiest way to move the tikzpicture up is to adjust its bounding box. All I did was to add

path[use as bounding box] (-3,-3) rectangle (3,2);

(and to do the rotate in a scope because otherwise it is confusing) to get
