OneWorld Payroll&World Financials

Does anyone have an installed client or a project where the customer has
existing World Financials and implemented OneWorld HR/Payroll by setting Payroll
not to coexist (since it cannot)? With this configuration, is there an issue
with the integration to financials in World posting to GL or AP from OneWorld
Payroll? Is there an issue with Vertex running the World version for sales and
use and then running a OneWorld version as well for the Payroll?
