If you're talking about a table top Pedestal Base (and not a credenza with upright mounting) then these two look like they would work.
The mounting brackets are height-adjustable as well as the main center post, and the VESA pattern goes up to 600mm wide.

I have a smaller version of the Swivel model on a 49" TV and it's solid. The height adjustability of the center post and brackets enabled me to lower the TV far enough to get the bottom edge an inch above the glass base and it looks factory like that.
