Sorbothane record weight?

I have an older b&o rx2 turntable that I am not comfortable putting much weight on, the spindle will probably not work with a clamp, and the tone arm is not adjustable so I am not interested in adding a mat.  It occurred to me that maybe a "puck" that doesn't weigh much could be made out of layers of sorbothane sheets and used as a low mass "weight" to damp record vibrations.  I have googled and searched forums and haven't found any hint that anyone has tried this. 

Is this a really bad idea for some reason I cannot think of?  I am certainly no expert.

these look like fun, but I don't know about getting them off, if they would last a long time.

Reflex record clamps are universal. They use a collet that holds the spindle whether threaded spindle or smooth. You have a spindle? You can use a record clamp.

True mc, but some guys here have a very short spindle.

I think 350g weight is perfect for any turntable, it's not heavy, most of the record weight are about 350g or less.

Assuming your records are flat just a puck of any weight is pretty worthless. The rim still can vibrate just as much. You have to use either vacuum or a system like SME, Kuzma and Michell Engineering.  https://www.youtube.com/watch?v=_viQuSUmEXY
The Michell clamp is very light and works great. You can buy one online.
Using these versions of the same idea flexes the record into the mat and the rim no longer vibrates. It will also flex out small warps, a puck will not.
