Actually a highshelf filter is used. In combination with the gain it reduces the part below < 700Hz, so when it is mixed with the <700Hz part of the other channel the lower isn't to much lifted.
And the phase response of the lp filter also will introduce a delay on the mixed part.
I guess using the mixer or filters for the gain is indeed just personal style. I the end I tune the pipe line gains to match other configs, just to minize the level differences between switch from one config to an other.

I think I understand that.  The filters I built will end up accentuating the bass frequencies because I'm adding some from the other channel and a highshelf on the treble frequencies boosts those a bit to compensate.
