Run service in reduced user role

If I am an Administrator is it possible to run a service temporarily on a Thing in a user role that is less privileged?

I am working upon a use case wherein the user is not an Administrator. For this I need to keep removing myself from the Administrator's group, check if the mashup/services work, and if they don't request other team member to add myself back to the Administrators group and keep working. I would like to avoid this.

Scenario is:

1. User Jack is an Administrator

2. When service GetData on a Thing runs it has to do it in a user role which is less privileged than an Administrator

3. Jack's user roles should not be affected in any way if this service runs.

Thanks,
