It would be ideal. The expected value for org-latex-pdf-process is a
command or a list of commands, but org-preview-latex-default-process
expects a plist of various processes and parameters. Maybe with some
conditional? 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. The argument could then be called simply
:process. E.g.:

Assuming the user has somewhere (add-to-list
org-preview-latex-process-alist my-process):

:results file :file foo.png :process 'my-process [or :process '(a plist)]

In other cases, like this:

:imagemagick yes :results file :file foo.png :process '("lualatex -interaction 
nonstopmode -output-directory %o %f")

wdyt?

Yes, I totally agree.
