Not really.  Even if there was `changing' a commit on the fly is not
possible without modifying the changeset hashes and altering the repo
history.

Why don't you build the files right _after_ commits?  If you have a
build script called `mybuild.sh' then something like this would work:

    [hooks]
    changegroup = /home/keramida/tools/mybuild.sh
    commit = /home/keramida/tools/mybuild.sh
    # To rebuild after every "hg update" too, add:
    # update = /home/keramida/tools/mybuild.sh
