Replicator dual clone upgrades?

[HoustonsProblem]

Hello,
I recently came into possession of an old Replicator Dual clone from like 2012 (Its from the now defunct company Imaginator 3d), and was curious what other kinds of modifications I could do to it? Ive ran off a bunch of prints and the print quality is surprisingly decent for a machine of its age (I've already added a cooling fan and duct which also greatly improved quality)

As far as I can tell the machine runs an almost exact clone of the firmware on the Replicator dual (most UI elements say "the imaginator", however if you try to run an X3G file for a different printer the LCD says "this file is not compatible with this makerbot." the imaginator also uses Makerware, which is makerbots old proprietary slicer, as well as its proprietary x3g file format) And I have seen documentation online about running Marlin or Klipper on the machine using an external raspberry pi

I'm curious if anyone else knows of any good suggestions or upgrades. I already plan to install a textured plate to replace the blue painters tape, as well as installing proper filament guide tubes since it has none currently

Also experimenting with the idea of an ABL or something if its even remotely possible 

And yes I completely understand the printer is basically ewaste at this point. I have two other 3d printers and have zero use for the replicator, but I would rather trick it out and make it modern than let it rot in a landfill, especially since it has dual extruders. 

If anyone has done this before or has any experience please let me know!
thanks in advance!

I am not familiar with that printer itself but upgrade path for old 3d printers are usually the same.

1. Upgrade the motherboard to something new (and with silent stepper motor drivers) and use marlin
2. Upgrade the hot end to something that fits your needs, like if you want to print flexibles, you would use a direct drive system
3. Upgrade the mechanicals (this i would say is the most complex upgrade), it might even be necessary if things are worn out.

If you want to keep the thing as is, you will probably have to mess with firmware. You can use klipper on a RPI but I dont have any experience with it, i prefer running marlin on the printer itself.

both hotends are already direct drive, but I'll keep the motherboard upgrade/replacement in mind
