We used to use a 50 fps per inch loss/gain figure when changing barrel lengths.  

You will have to substitute more air per shot to bring the velocity back up.  Lower shot count due to more air per shot.

Have you considered a 14" or 16" barrel?  Much less impact on performance…..and it is a noticeable difference in length.
