Not to take away from the validity of the wish, just offering some options:
The Morph Tool could be an alternative here. It can do most of the things the Mesh Tool can do, plus any of its edge can be hidden, plus its 2D is a true 3D projection.
I also think the Morph Tool is a more robust tool so it can handle such large complex geometries better.
Also, to start experimenting with this, you can simply copy a Mesh, then convert it to a Morph and see how well it handles stuff.
