I can't really say, I just use IBO with D5 and D6, and they share the
same directory provided that the dcus go in a different path for each
version.
I think that duplicating the source can be a source (:-)) of confusion,
but perhaps different directories for the *project files*, in which you
put the directives for the dcu output path could be a nice thing.
Something like

IBO4
Samples
Contact
<all the pas and dfm files>
D3
Contact.dpr
(uses the files in ..\Contact and outputs the dcus in the current
directory).
D4
Contact.dpr
(uses the files in ..\Contact and outputs the dcus in the current
directory).
D5
Contact.dpr
(uses the files in ..\Contact and outputs the dcus in the current
directory).

Did you mean something similar?
Ciao
