Mark — 
You’re right in the mapping between IOS-XE and IOSd blobs.  Based on the older architecture of XE — there was a direct correlation between XE and the IOSd blob that was running for most of the control-plane bits.

Now that IOS-XE has moved towards “open” IOS-XE — with a drastic difference in architecture — 16.6+ is quite different “under the covers” than 3.x versions; not that you’ll see much over the top.

Either way — the upgrade won’t be bigly different.
