If the two wikis share the same wiki.d directory (same custom $WorkDir), 
and if both the group and the page names are the same, then it is 
possible.

If they share the same wiki.d directory, and if the group and/or the 
page are not the same, you in one you can read the variable from the 
other:

  in Group1.Page1:  {Group.Page$:VariableX}

Or, you can make PmWiki believe the page name is Group.Page in 
config.php:

   if(preg_match('/^Group1[.\\/]Page1$/', $pagename)) $pagename = 
"Group.Page";

but then PmWiki will read from the file Group.Page not from 
Group1.Page1.

To send the browsers to the other domain, in the .htaccess of 
example.com you can add a redirect:

   Redirect temp /Group/Page  http://www.example.org/Group1/Page1

(or "Redirect permanent ..." after you tested it and it works as 
expected.)

If both domains operate from the same document root, as well as share 
wiki.d, you can also use url rewriting:

   RewriteEngine On
   RewriteRule ^Group1/Page1  pmwiki.php?n=Group.Page [L]
