If you want to use the TCL route in Workbench you could use the FME_BEGIN_TCL directive to test for the file and submit a dummy dataset if it doesn't exist. See...
http://www.fmepedia.com/index.php/Category:TCL_Pre_Post_Processing_FAQ If the dataset exists, but you don't need to read it, then what you can do is use the 'features to read' setting available in 2006-GB. Set this to 1 to read just a single feature, or use the Sampler with a similar setting to drop everything. By publishing either parameter you'll be able to set this easily at run time.
