I would suggest figure out your how you work best first, then make a plan. What time of day are you most energetic? Are you more efficient working on one task or multitasking? What is your efficient number of tasks at a time? Are you better at large or small blocks of time? Figure this stuff out first. Fighting against your "natural" routine, who you are, will make any schedule more difficult. It drains energy that is best used elsewhere. Work with who you are and the way you are.
