The --splicemap option to hg convert should let you do what you want. Do 
the checkin into one hg repo, and the convert into hg another (using 
whatever conversion tool you are using, hg convert or otherwise). Then, 
with the ci repo as the dest and the convert repo as the source (so 
you're doing an hg2hg conversion!), do:

hg convert --splicemap mymap.txt [repo from step 5] [repo from step 6]

mymap.txt should have a single line:

[full sha1 hash of first rev of converted history] [full sha1 hash of 
initial import ci rev]

(that is specifying that the parent rev of the first rev of the 
conversion to be your initial import of root_changeset rev).

Hope that helps.
