Then, resume bitbake from step B, and after that completes then again regain control and run some additional transforms.  Finally resume bitbake from step C and let that run to completion as well.

Don't do that.  Bitbake will have no knowledge of your intermediate
out-of-band changes.  Just write tasks that call the signing tools as
part of the build.
