Exactly. By fudging the metadata you're not going to get lens corrections, the colour will be off and you'll have to create your own profiles, etc.
You could probably get the colour where it needs to be by using Lumariver Profile Designer, which allows for the creation of C1 profiles, but you'd still be out of luck on the lens corrections. And, particularly on the wider lenses, these are useful.
So it's doable, but you have to question the value of jumping through the hoops to end up with something that is never going to be properly optimised.
