I also want the same thing, however Tim said that they aren't going to make any. Not even for more money :(. I can understand though, if they didn't already have a casing it would be pretty cost ineffective to manufacture a new one just for a few people.
But perhaps if there are enough of us it might be worth it, you could shoot him in email to let him know more people are intereasted.
That EMG to Lundgren swap looks awful and ring mounting pickups negitivly affects the tone and makes the guitar more sensitive to vibrations.
Hopefuly the new blackouts force EMG to make standard sized pickups and phase out the old bass sized 7 string pickups so routing won't pose a problem for 7 string replacements.
