An interesting concept.

In principle, yes. Features in EMBOSS follow the GFF model, so they are stored
as groups of start and end positions. Assuming that they are not one of the
more exotic kinds of start and end positions, it is easy to 'insert' one
feature table into another. Deletion is also possible, although ends of
features within the deleted region rules out making the process completely
reversible.

I have seen it all before - in the EBI's NEWFEATURES editor when mutating the
'replace' qualifiers.
