I'm not sure I understand your question. You want to have two objects 
fixed together, but periodically change their positions?

ODE does not provide a function to detach joints. Since FixedJoints 
don't have any state, you could probably destroy the joint, move the 
bodies, and create another one. However, be aware that the manual says:

"Using this joint is almost never a good idea in practice, except when 
debugging. If you need two bodies to be glued together it is better to 
represent that as a single body."

Hope this helps.
