Is there a Physics engine that does trimesh-trimesh collision well? I've found that many packages only support simple convex shapes like spheres and boxes, like ODE, and there are a few that support convex polyhedrons.

Saying only support simple shape is and over simplification, that maybe truth for ODE for not for any other engine. Actually all mainstream physics engines (except ODE) support general convex polyhedron collision.

Triangle mesh to triangle mesh is and impossible to solve problem geometrically.
There are few algorithms that are using image precision methods like quantized voxel spaces, or Z depth buffer that can be adapted to use graphics hardware, but nom of then are generics enough to be used as a backbone collision system of a general-purpose engine.
Even those methods cannot handle completed generic mesh, as the mesh must be airtight.
