Thank you all for the helpful advice. I really like the Torklift system but honestly more than I care to spend (almost $2K). I'm going to look for a 2.5" hitch with the 24"-36" extension bar and that will be $500-$600
You guys are right, there's no 2" extension bar at 24". What was meant was getting a 16" extension with my standard ball hitch adapter that gave me 24". The only problem there it's only rated at 3500 lbs and 350 TW. but I have seen those 2" extensions that I can customize.
Making my own is still interesting but your right. At my own risk and without any testing or knowing. My real vision was starting with a 2" solid shank in the receiver, going into a 2 1/2" tube (reinforcing with a 2" tube inside of it) and then ending with a 2" drop (or whatever is appropriate) and ball like a standard hitch. Just one piece from the first pin on the hitch and with the chain system similar to the torklift and Reese extension (in a triangle shape) from the outer edges of the hitch to the extension. I feel like it will work and be plety strong but then concerned about the stress it will put on the 2" hitch and how that will also have to be reinforced with gussets and by that point I go back to the 2.5" hitch with the 24-36" extension.
I will still measure tongue weight but think the 2.5" hitch with the 24-36" extension is probably the best bet
