Can one Communication site show content from another Communication site?

If I have 2 Communication sites attached to the same Hub can they display each others content? For example, if I have HR hub with associated communication sites for western region and one for eastern region, could I show the information for the western region on the eastern regions communication site and visa-versa? If yes, what form could it be in (news ticker, card, just a link to the other comm site, etc.)?
