Hmm, tricky one then, is there a general consensus on the best version/design to look into?

From a quick look I think the Ormerod 1 version may be compatible for all machines with the extra slot for the ribbon cable. The position of the drive belt and end stop holes would need to be checked though. The largest holes from the different versions would be ok as strength would not be an issue. The last version was obviously an attempt to stop the acrylic splitting and provide more rigidity with the hooks into the extrusion.
However.... I'm not convinced that just replacing the plate will solve problems such as adjusting the bed and keeping everything square. You will still have the idler mount and motor mount as printed parts that hold the axis end plate in place and square. These are parts that tend to split at the countersunk holes and would in my opinion still allow some flex, with the squareness dependant upon the accuracy and strength of the printed part. I also found that the weight of the machine on the end plate foot made it very difficult to adjust. That is why I went with the idea of a frame to hold the end plates and remove the weight of the machine from them.
My mods are on Thingsverse if it's of any help.

Note 2
Looking at the thingyverse pics, I see we have the Y end plates connected to the motor mount which is in turn connected to the frame?

I meant the position is not critical in regard to the alignment of the y-axis rails.Quote

The position of the motor mount may be critical for the cable lengths. So if you switch the mounting position for one machine type the cables could be too short. I guess that the Ormerod 2 could have a bigger problem.
However I would give some modified brackets at thingiverse a chance where the motor bracket is one part with the y- bracket and where the brackets are thicker and therefore more stable.
I can confirm that the original y-brackets easily break at the countersunk screw holes.
