BSP Data Entry Application in a SAP BW System

Would it be unwise to develop a BSP data entry application within a BW system?

The application's purpose in life is to collect data for reporting in BW.

The application would store its data in transactional ODS tables. From there, the data would be extracted and loaded into the InfoCube for analysis and reporting.

Your words of wisdom would be appreciated.
