If I upgrade my domain to AD 2016 can member servers with Win2003 still connect to that domain ?

That probably doesn't answer your question.  It doesn't look good.

If it is a member server (not a domain controller), it should be able to connect.

DFL and FFL concepts apply to domain controllers.

The combination Windows 2000 member servers / Windows 2012 domain controllers worked (but possibly with problems):

https://social.technet.microsoft.com/Forums/windowsserver/en-US/a6070b2f-827c-4337-81ac-ffa0a1a08bf0/windows-2012-dcs-and-windows-2000-member-servers?forum=winserverDS

Of course, since Windows 2003 is no longer supported (and probably was never tested with 2016 domain controllers or even 2016 member servers), it might be challenging to resolve a problem if a problem does occur (application level: IIS, SQL, etc).

What role the will 2003 servers play?

Do they at least have the latest services pack (SP2 I think for 2003)?

Definitely yes. I have one last 2003 member server and a domain operating at the 2016 functional level. There are no problems with that 2003 server being on the domain.

Thanks Joe and Rob. I always like simple answers that are confirmed with experience.

You don't have by any change a MS article that describes that ?  As much as I appreciate your advice, an MS article looks better in my report :-)
