I guess you can do it with a combination of the existing tools:
You can create a buffer zone between your 2 dataset where they merge and
set the buffer to null values. Then using r.fillnulls
(http://grass.osgeo.org/gdp/html_grass64/r.fillnulls.html) and you can
fill the gap using both datasets.
Hope that helps.
