Exchange 2000 with NT4 and Exchange 5.5

We would like to take advantage of the new features of OWA for Exchange 2000. Can we do this without migrating our entire 8 domain NT4 setup with 8 Exchange 5.5 sites. Can I just run one Win2000 server with OWA and running the exchange 5.5 connectors.

Our local users would still connect to 5.5 with Outlook but remote users could connect with Outlook Web Access on Exchange 2000?
