Yes I think 20 grams should be feasible. I could also try to make an extension board with XBee sockets + GPS. The problem here is the connectors might add a lot of weight so we would need to optimize that.
Oops! I meant Gluon of course!
Now that we are getting down to those low weights, cables and connectors become the major things to save weight. Like 'penguin' suggested enameled wire would be lightest but I will look at some flat cables between Rx->GP->GPS etc and see what hardwiring could do.
