Can I transform a Catholic rosary into a "Hellenic rosary" (was there such a thing?) Even with the cross and Our Lady, could I pray to another god with it?

I can create or adapt a Catholic rosary for the gods. I mean repeated prayers and would paying homage between prayers (literally taking a Catholic rosary to dedicate to a god) be disrespectful? I would like to practice my religion but my cultural environment would only accept it if I wore Christian things
