So a ton of requirements. You need to first pick a region that has the required hidden resources. Basically any historically Hellenized or significant province. Next, your empire must be large enough to support the addition of more Dynastic Administrations. By default you can support 1. At 12 settlements you can have 2, and at 25, 3. BE WARNED: do NOT dequeue the Dynastic Administration once you've queued it, or the empire size script will PERMANENTLY lose track of it. Finally, you must Hellenize the crap out of it. A level 2 poleis and level 2 Hellenistic colony are required, totaling at 3 colony points. Unfortunately to answer your question, Roma cannot support a BP, since it was neither historically Hellenized nor is a "royal core". Try poking around descr_regions and descr_strat to see which settlements fulfill the hidden resource requirement
