First of all, restructuring seb_one is highly not recommended, the person who made it, Alex, has done some calculation so the template perfectly fits into multiple devices
As using seb_one is bit like playing puzzle.. i would like to propose this scenario:
1. Move fields in Sidebody-A to Bottom-A
2. Move fields in Sidebody-B to Bottom-B
3. Put Title in Mainbody
You'll get similar site structure as you describe
