The Triplanar can be mounted on the Technics. I've done this for a few Triplanar customers to which Lew refers above. To do this I designed an armboard machined of solid aluminum that fit where the original arm mounted, such that the result was a surface at the same level as the rest of the plinth. It was then possible to mount the customer's Triplanar arm. In fact we've even been able to mount the 12" Triplanar.
The original arm is pretty good- I would not bother replacing it unless you get something *significantly* better and most of the arms previously mentioned are not; mostly, they're just different. I am a fan of the Triplanar as its one of the very few arms I've heard that get everything right on LPs that I recorded; IOW it *is* significantly better, but also costs more than the turntable itself. But the 'table is very well designed and does justify this sort of upgrade.
