Mori Seiki MV-Junior Retrofit

Basically, as much as possible. Has got hands on an old running mechanical fine MV-JR. It is disassembled for transport and the plan was to fit it back together next year. And now standing at a crossroad, keep the old Funic system 10M controller or change. I didn’t have experience with this old controller and therefore was thinking retrofitting. Your solution looks more ideal at given time. I had taken a quick look at the diagrams before you posted and had an idea it was possible.
Due to this basically as much as you want to share.
Another thing, interesting few Scandinavians in this thread, Danish here.

Hi.  Andre Fellow Norwegian here. Is it possible to talk to you on messenger or something?

     Hello, i will receive next week a Mori Seiki MV-40B (year 1989) with fanuc servo motors and drives and i want to keep old fanuc servo motors and spindle motor. In your opinion is better to reuse old servo drives or change with ethercat new models? (i dont know if will be problems with fanuc encoders)
I have already, touchscreen, linuxcnc pc, mesa board7i96s and 7i85 . 
Any advice is very apprecieted. By the way, very nice project you made
