AIUI wormhole mouths don't have a direction. They're spherical.

The picture of a wormhole as a bell-shaped indentation in a sheet, like the graphic on this article, is an artifact of trying to explain 4-d concepts in 3-d shapes (in 2-d images). For a being in the 2-d sheet, the wormhole is a circularly symmetric spot of weird-shaped space. In real 3-d space, a wormhole is a spherically symmetric spot of weird-shaped space.

True. You could still use this to make two Lagrange points near the surface, mucking up everything. The fact that the hole has to be longer than the distance traveled would greatly reduce the gravitational field coming out of the hole.

You could still drop one end of the hole into the sun... (and I’ve just realized this was a Farscape plot and therefore how the idea got into my head in the first place)
