Hi Norm,
Thank you for your quick reply.
Yes, the thought is to mount it on an 18" base suitable for most normal mowers.
I've just taken some night photos to add those above that may help further.
It's currently a 3-bolt mount to the plastic frame on the Lawn Beetle shown here:-
The plastic mounting posts are approximately 30mm-35mm high:-

The current blade cutting boss is on a keyway spline:-

Difficult to see to get more specifications of shaft sizes, at the moment, but can check out further tomorrow if it is a feasible option to do the conversion.
Cheers
