One late follower, glad you like it.
I personally woudn't say that the mids are more forward after the modification, IMO they become more natural and better integrated in the overall tonality. And I think that it is vice versa, we have rather less amount than stock - whenever I put on a stock Gradessandro, I get really underwhelmed by the way the mids scream onto my eardrums.
To the bass, adding only more distance would indeed lead to a thinner sound. But as we are using the GS1K pads after the distancers, we get a (sort of) "bass lense effect", which does not only compensate, but also increases the bass layer complexity.
I still recommend trying the pad lining described in #1, the music coherence gets a nice edge from that.
