complementing the data used by your experiment with other sources is not a problem. In fact, if your experiment is part of an ongoing project, it is understable that you do not break your implementation to interact with Organicity.
Said that, it is also important that you interact with Organicity, either consuming or creating data. You may consume data that can be afterwards complemented with external data, or you can feed Organicity with new data created by your experiment (ultimately you applications).
Please, let me know if it asnwers your doubts.
