Is there any issue with just following the schedule template in https://www.umb.edu/editor_uploads/files/cnhs_files/CNHS_Trad_Curriculum_060110.pdf which covers 8 semesters of course work in 4 years? If you started with AP credit that fulfills some requirements, you can replace those requirements with free electives, or possibly take some courses in the template a semester early.
Since it looks like the honors program requires only substitution, it is your call as to whether you prefer the substituted honors courses, in context with any other benefits of the honors program.
