The cost alone would be more than buying an A model bike. Be easier to transfer police panels etc to an A model
I put the pics in to show the visible differences
But you would need at least:-
Apart fron the visible stuff there's the ABS electronic inside LH fairing so LH air tube has to go
Instrument cluster - A model has traction control and ABS warning lights

A model front forks as
new front forks as anti dive system is on RH for on ABS version
Brake delay valve above calliper
secondary master cylinder on left fork
New coolant overflow bottle which goes to RH rear of motor
front and rear ABS modulators, (rear one goes into base model coolant overflow position
Traction control on/off and ABS warning reset (?) switches below LH fairing pocket
