Very interesting. I think there is no way you could use Traits as
extensively as we use it in Traits-based project, doing reactive
programming using Traits callback. However, for a small use, this seems
like a good idea.

I wonder whether you shouldn't simply try to patch Traits, as there is
only one C file. So you could provide a replacement to it. I don't know
what Dave Morrill (the author of Traits, for those who do not know) would
think about this, but I think it would be a good idea.

My 2 cents,
