yes, the solution i would suggest, is to create multiple "molecules",
draw into them and then show only one of them. check out the
multimolanim plugin as an example for that. this was created to work
around the limitation of VMD that all frames have to have the same
topology data, but it should work for you just as well.

in case of mpeg generation, you have to use the "user" function method
and supply a function that toggles the display between multiple
molecules. you can probably "steal" the guts of that function from
