If it uses stepper motors, then adding on one of the common RepRap controllers should work fine. The common firmware versions are very configurable and should be able to handle what looks to be a basic Cartesian mechanism. Your biggest headache will probably be sorting out the wiring harnesses.

... the mechanical setup is common for RepRaps, you only need to identify the wiring and needed voltage for the endstops and if the motor drivers are common STEP/DIR types - then any RAMPS or other Arduino with BOB would be suitable ...

Also check out what the voltages and amperages are for the stepper motors. The A4988 stepper drivers are maxed out at 2A but need active cooling fans and cooling elements on them in order to supply those 2A. Above 2A it would be good to check out other stepper drivers. I've used 2.5A stepper motors successfully with the A4988 drivers but anything above will need a different approach because the motors will lose a lot of torque if underpowered.

This something I am curious of. Can you post pictures of the inner mechanical parts? I would love to see the guts of that thing.

There are polulu style drivers for ramps that supposedly can handle close to 3A. 1.5A per phase. They might be worth buying if the stock drivers don't work so well. I believe they are the DRV8825 drivers. Correct me if I am wrong though.
I doubt the stock electronics on that printer have segregated drivers. Reusing them may require a bunch of EE experience and a whole lot of circuit tracing and redesigning.

I'd really like to keep the DC motor/encoder setup if I could. It is a strong motor (265 in-lbs) with a very fine resolution 1000 ppr. It's not the norm and it may cause some extensive troubleshooting, but reverse engineering this thing work is 90% of the fun for me. In my opinion, the only reason to get rid of the DC motor/encoder is because it's not "supported" by normal hardware/software/firmware. Would you guys agree?
I think I'm going to need the extra torque to be able to pull the filament a long way up through the tube

I have heard that some drivers out there turn the DC motor/encoder into a stepper compatible solution. It may work. Honestly it is an ideal solution if it did work. However finding how it works may prove to be a challenge. There has been research done in the possibility of using a DC motor and encoder setup. However it seems there is not much headway for it. It seems pretty difficult to attain accuracy.

The accuracy is a benefit IMO. I'd be able to easily fine tune the feed rate with the feedback from the encoder. I've worked with motor/encoder before and it was excelled for positional/speed accuracy. If Stratasys decided to go with this setup in a $50,000 machine, I think there is a good reason.
EDIT: I'm nervous that the board I go with is not fast enough to deal with the interrupts of the encoder and deal with everything else. That's why I'm thinking of having a separate board to dedicate to this sub-system.
