WordXP Dutch together with OfficeXP English?

[Dutch User]

I use an laptop (XP Dutch) that my employer set up with Office XP English
(it's not a volume licence)

Combination works fine, but there is no Dutch proofing, grammar, Dutch
samples etc
(and my employer won't provide the proofing CD)

Solution (?):
I own a legal full version of WordXP in Dutch (still boxed)
Is it possible to de-install the English WordXP component (from officeXP
English) and install
the Dutch WordXP in a different directory
without crashing Office?

I'm worried about the "microsoft shared" Office10 components,
but I don't mind having a mixed GUI as long as it works.
