I guess we'll never know.

Nope, won't work. The way GPS works (really simply) is all the satellites have atomic clocks on them, and broadcast their time. The receivers are using the differences in time from the satellites to figure out how far it is from each of them. Trying to relay the signal changes the timing of all of that and wouldn't work.
