Just something to think about but one of the problems with doing less than a full wort boil (ie; the wort is highly concentrated and you water it down going into the fermentor) is that your hop utilization is going to absolutely suck. Hop utilization drops in high gravity situations. Additionally, if you boil for only 20 minutes, you are only going to get a fraction of the utilization that a 60 minute boil is going to give you (generally about 28% for a 60 minute boil, normal gravity wort, whole hops). What that means is that you will need to greatly adjust up the amount of hops you are using to get the bitterness you are looking for (maybe as much as three times normal). One thing you can do to help is use hop pellets as you tend to get better utilization from them but I gather reading the posts on this board that you gents generally use whole hops.
I bet I haven't brewed an extract batch in over 15 years so I'm really not the best one to advise extract brewers therefore take that for what it's worth. By the way, you can brew some damn good beer with extracts if you know what your doing but it does make it a bit harder when not doing a full wort boil. Anyhow, good luck and have fun.
