WOuld it be possible to split the input signal into two seperate paths, one that is split into 3 drivers, and another the is spilt into two other drivers that overlap the crossover points of the other signal.
What would this result in?
I know the Ohms at the amp would be halved, but what kind of frequency response could be had. I mean, could this technic be used to fill in the dip/gap that most crossovers cause?
Or would it just be easier to design a high order 50+dB per octave crossover?

If I understand you correctly you are looking for a 5 way crossover, right?
Here is the information, and
here are the calculators... Figure EACH crossover point individually, rather than thinking of it all as one. You'll have one high pass, one low pass, and three band-pass figures. The amplifier still will only see a fixed impedance (mostly...) no special figuring necessary.

It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice. You should write it down."
Ahh, thank you.
I didn't realize that you can make individual bandpass filters like that, most of what I've read only gave info on highpass/lowpass type filters and stringing them together for additional speakers.
Thank you.

Just don't expect great results with a text-book crossover design. Crossovers really need to be built from actual testing of the drivers and using a program like Praxis to help in the design process. Also, multiple crossover bands become even more difficult as each one will effect the response of the other.
Why are you trying to do a 5-way design? You should be able to fill pretty much the full bandwidth with a 3 way design without any issues of early compression or early roll-off. It's just a matter of selecting the right speakers.
