These mods really shouldnt hinder you. I used the 8 foot bar plans (without a kegerator) and made it right around 7 feet and it wasnt a problem. I am no expert woodworker by any means but was easily able to make the changes I needed to make the bar smaller. As long as your able to work a tape measure you should be fine. There is still plenty of room for your kegerator (im planning on building one soon into my bar), you will lose a small amount of storage under the bar but it shouldnt be a big deal. The only changes that you will have to do require the tape and not following the exact cut list for the bar. shouldnt be that bad. If you have questions let me know. I have pics in the gallery if you want to see what a shorter straight bar might look like.
