I assume I would:
1 - call beginInsertRows on both models,
2 - insert the row in my single data structure
3 - call endInsertRows on both models.

Sure, you can look and see that the size() of a QByteArray returns
an 'int', but that is only as of today. You should get into the habit
of controlling the types written to QDataStreams.
Actually, for reading and writing binary data files, I think it is wise to get
into the habbit of using

Some tool kits use a buffer in their version of QDataStream.

All of the following is IMHO:
I think that if you are going to read the size back as an 'int'
you should insure that an 'int' is written in the first place:
