I think it's certainly possible and that's one of the reasons I've not indulged and bought one. I would hate to spend £300 on a putter that a year later I'm not allowed to use and I can't even give it away much less sell it. I just decided to carry on with my 35 inch putter with the top inch of the grip above my hands and pressed into my left wrist - like a miniature version of arm-lock.
Why not just buy a cheap putter and have the shaft extended? Low cost solution to try it out ?
