no. this is not (currently) possible. selections in VMD can only
be for a single molecule.

if you want to merge two pdb files, you can just use a text editor.
just remove the END. if you have .pdb/.psf you can use the mergepdbs
script from the script library (provided you are using the CHARMM
force field).
BTW: you can find this by sticking the following into google:
merge pdb files site:ks.uiuc.edu
restricting the search with site:ks.uiuc.edu is in general a
good way to search _all_ available resources on the TCBG servers
at the same time. ;-)
cheers,
axel.
