Sputniks,
Before driving yourself too crazy, try to determine if an arm could be mounted at some slightly different point on your table. Being able to vary the mounting point just a few mm closer to or away from the spindle would open up a much larger field of tonearms.
***
However, IF your spindle-to-pivot dimension is FIXED at 225-226mm, then your table was designed for an arm longer than a Rega but shorter than a TriPlanar (just to pick two examples I'm familiar with).
Regas have a stated mounting dimension (spindle-to-pivot) of 223mm, although 219.5-220mm works better. A TriPlanar has a mounting dimension of 233.5mm. Obviously Oracle had something between those two in mind.
A Rega has an effective length of 240mm. A TriPlanar has an effective length of 250mm. For the mounting dimension you stated you'd need something in between.
