Is it possible to take multiple UVLayouts (for geometry with baked textures), and arrange them in a UDIM tile layout? I'm hoping to take this to Substance Painter for painting over.

you can assign UDIM prim attribute to your individual geometries

then assuming your uva are on vertices and in 0-1 tile, you can do Vertex Wrangle to offset uv's to individual UDIM tiles based on prim udim attribute

int udim = prim(0, "udim", @primnum);

udim -= 1001;
v@uv +=  floor(set( udim % 10, udim / 10 ));

and rename your textures with corresponding UDIM token
