You have some good points,but any plane will fly even if wing area, wing chord wing planform, tail moment, horizontal tail area and chord and planform are not correct Those are just rule of thumbi ideas and dont have to be followed,there are alot of odd aircraft out there that dont follow standard rules ,and these rules change with the desired function of the acft .it might not fly well but it will fly. The only rule that needs to be followed is the rule of CG and that is a function of center of lift. If im understanding the OP's request its was for finding the CG on a plane he modifiedKiwi4
