Yes, it's a good idea since a bridge sitting on the rim doesn't move the soundboard all that well. It would be nice to be able to get it even further from the rim, but there is a practical limit in a grand determined by hammer clearance of the belly rail, and the upper limit of the speaking length of C-8.
