Is there any ill effect from deleting a 2nd version that was used to create a 2nd TIFF sent to an external editor?

I have an original that I want 2 different results for. I make the first result by simply sending the image to an external editor, which gives me a TIFF, and I make my edits. Now I want to either use the original or this TIFF as the basis for the 2nd result. Either way, Aperture creates a new version which I can send to an external editor and have my 2nd TIFF. I now have the 2 TIFFs (2 results that I wanted.) Can I delete the 2nd version of the original that Aperture created will no ill effects?
