Building a second robot - electronics?

[trycatch]

When trying to do the two robot thing, do you HAVE to have two sets of electronics? Can you use that as your weight allowance and transfer that off your second robot back to your bagged robot at competition? We have a decent influx of funding this year, and I'm stewing on trying to do the second robot thing, but it would eat up a ton of it to get two sets of just the base electronics... the roboRIO, PDP, router, breaker, VRM, etc., etc. Does anyone else swap before bag?
