Yes, the relations file can match on role. I have never tried writing
relations rules for multipolygons, though.

Something like this (not tested) in the relations file of your style
should do the trick:
type=multipolygon & natural=water { apply role=inner { set natural=land
} }
This will assign natural=land to each inner member of multipolygon
relations.
As far as I understand, it is not possible to write other conditions
for the apply than role. And you cannot match role by regular
expression. In this case, you cannot add a condition that you only want
to set natural=land for those inner members that had natural=water.
I do not know when the custom multipolygon processing kicks in. It
could be that the style rules are executed after that, and it is too
late to adjust anything with style rules.
Best regards,
Marko
