Active X/O piggyback

Whilst saving up funds for a Berry Ultradrive is it possible for me to use two citronic cx-23's in 3 way mono piggybacked to allow bi amping of the mid tops whilst the first X/O deals with sub and lower bass?
It would mean feeding the audio to the second x/o from the 3rd mono output, this is just a get by situation for testing until I get the Berry

Nothing wrong with that, you can route the signals pretty much anywhere as long as they all stay in front of the Amp.

Thanks Tony, its just until I can get a berry sorted
