Division of tasks

Notwithstanding the workload, do you think this is feasible or are there any potential conflicts of interest here?

Answer: A single person to manage such scope (considering the different systems, number of personnel and multiple offices), may compromise the systems effectiveness, because not only the common aspects of the systems (e.g., control of documents, internal audit, processes and controls monitoring, etc.), but the specific activities required by each system (risk assessment, business impact analysis, and processes monitoring), and support required by employees can easily overload a single person time and capacity.

You should consider at least another person to assume part of the tasks.
