Well, yes and no (mostly no - but see below):

o You can of course customize this variable, but that's a global setting.

o You can use the ":latex-image-options" property to set the above variable,
  but that is used in org-publish-project-alist, not for exporting. From org-exp.el:

,----
| (defconst org-export-plist-vars
|   '((:link-up		      nil	  org-export-html-link-up)
|     
|     ...
| 
|     (:latex-image-options     nil	  org-export-latex-image-default-option))
|   "List of properties that represent export/publishing variables.
| Each element is a list of 3 items:
| 1. The property that is used internally, and also for org-publish-project-alist
| 2. The string that can be used in the OPTION lines to set this option,
|    or nil if this option cannot be changed in this way
| 3. The customization variable that sets the default for this option."

`----

o You can modify the setting of the org-export-plist-vars (either by modifying your copy
  of org-exp.el or by some other method) to change the line

     (:latex-image-options     nil	  org-export-latex-image-default-option))

  to

     (:latex-image-options     "latex-image-options"	  org-export-latex-image-default-option))

  and then use

     #+OPTIONS: latex-image-options:width=1cm

  in your org file.

  [BTW, if you are using git, small local variations from the canonical org-mode can be easily
   accommodated, by using a local branch and git rebase.]

o You can try to convince Carsten that this should be part of canonical org-mode.

HTH,
