If I was doing this just for my self to keep then yes I'd probably take a route something along those lines or whatever got the job done. However, this has to be done with selling the machine in mind. So I wouldn't want any bespoke boards etc which would cause a buyer hassles in the future, because the hassles will just rebound back to me.

Saving money isn't a priority but with that said I do need to keep an eye on the budget because it can easily run away. This why industrial controllers are off the table because the machine while still very capable is still 25yrs old with a much reduced resale value and it's highly unlikely to ever see use in an industrial setting again so we cannot command the prices asked in Industry. Any new owner is most probably going to be a serious Hobby or small business user and they won't pay industry prices.

The main priority is ending up with a Reliable machine that uses off the shelf modern components, along with a controller that works and has a decent support network that Hobby or small business person can access freely if required.
Linux CNC/Mesa are proven with massive following and support so I've no concern in this department. Likewise so Is Kflop and Centroid and again wouldn't hesitate to use either of these.
However, LinuxCNC/Mesa are favorites because of the budget and the fact the others offer nothing more but cost more. All of them are new to me at this level with Servo's etc so whichever there is a learning curve to deal with. But I like the challenge.!!
