Diff'ing Model Stores

Greetings...

We're running AX 2012 FP (Yes, I know) and doing model store deployments.  Before each deploy, I bring my production DB into my staging environment and export the model store.  I then sync (force) with TFS, compile and sync and then export the new model store.  (All well and good.)

I would now like to be lazy.  (Let's call it a double check instead.)  I would love to be able to diff the two model stores and determine if any Data Dictionary objects (any model / layer) have changed.  The reason being is that if none have changed, I believe I can deploy the new model store and avoid the compile & sync.  (Right?)

Anyone have any thoughts / comments / suggestions?  (Dire warnings?)

Thanks,
Bob
