Is it possible to have both a Positions and Jobs setup under the same Legal Employer/ Business Unit?

The company in question has a large, decentralized population of hourly workers with very high turnover who operate in a Job Management structure as of today. Their managers sit in a traditional structure that would benefit more from Position Management. The hourly population reports directly into the Managers, and sit in the same Legal Employer and Business Unit. The question is whether the managers could sit in positions while the hourly population utilizes job management?
