Yes, in my opinion it should work in principle, but it is not ideal. In exceptional cases, it could also go completely wrong. If possible, I would use the same RAMs. By the way, the bars are really good - they deliver what they promise. I wrote above that the RAMs in my board (Asrock B550M Steel Legend) don't quite manage 3600. With a new firmware of the motherboard, 3600 is now also possible with the specified XMP profile.
