Until there is something built in to `hg convert`, you'll have to hack
something together.

You could try creating a custom filemap for convert that ignores the large
files. Then, do the conversion. Then, create a new repository and `hg pull
-r <rev>` the converted repo in up to each commit where a large file was
modified. Next, manually (re)create the commit (with largefiles support),
adding largefiles integration where needed. Then, pull and rebase on top of
the new commit. Repeat for every commit touching a large file.

If you only have say a few dozen commits touching large files, this
shouldn't be too bad. If it is more, it might be easier to add largefiles
integration with convert (which sounds like a very useful feature to me).
