Unless you are a Civil or Mechanical Engineer and can do all the calculations to confirm that your redesign is in fact "equivalent", I recommend you follow the manufacturer's design and specs exactly
Larry, Having installed a 70 ft self supporting tower in 4 parts of the US, and seeing for myself the complex stresses imposed on the base, I wouldn't deviate from the manufacturers' specifications.
I believe that AN Wireless also does this. It probably saves on concrete however it is a significant amount of work. I do not recall what Rohn does with their SSV tower bases. Does the Trylon have an
Rohn gives the specifications for three foundation options as shown in their pdf linked here (shortened to avoid wrap issues): https://tinyurl.com/ybq2fkzj I have a 120' SSV but the cost of the found
