I am attaching a new patch with this idea incorporated. I have also
changed the name from full-to-pdf to standalone.

Best regards,

Subject: [PATCH] lisp/ob-latex.el: Add two new header args to LaTeX block.

* (org-babel-execute:latex): `:process' allows modifying the value of
`org-latex-pdf-process' or `org-preview-latex-default-process' in a
specific block.  If only the `png' extension is provided (without the
`:imagemagick' argument), then the expected value is for
`org-preview-latex-default-process'. In all other cases, the value is
for `org-latex-pdf-process'.  This argument has no effect if the
conversion is to `HTML'.  The `:standalone' argument requires that
the LaTeX block contains all the code necessary to be compiled, as if
it were an autonomous LaTeX document: the expected result will always
be a PDF file.
