advise options needed on laser upgrade/add on

The laser assembly could be mounted on the machine without any problems. This takes away the need for long flight tubes, beam paths and alignment issues.
What materials and thicknesses are you thinking of cutting? For steel at anything above thin sheet material you will need alot of power.

I don't know much about lasers (have had a 900x600 60W machine for about 3 years now and have never managed to set it up!!!), but if converting a commercial cnc router I would have thought it best to use a fixed head, moving XY table machine so that the Z axis is only used for the focal length. G.
