Not specifically for vibrations, but you could do a Helibar Plate handlebar adapter with the existing bars. At least that gives you a wide range of rotational adjustment of the bars, raises them, and they are back roughly 1.5" more. Bar position can make a difference in the angle your wrists are at. I had mine at the full forward/widest position and found that worked best.
On my CBF1000 I put some 31" wide Emgo handlebars on, essentially wider like dirt bike bars. They were only 7/8 diameter, don't know that they reduced vibes a ton, but were similar ergonomically to the Helibar setup. On the Versys 1000, the bars are similar, 1" diameter tapering to 7/8" where the grips mount. Quite solid bars, didn't have to do anything else, instantly comfy. Similar ones are ProTaper, Renthal, etc.
How else to get rid of vibes.... loosen the exhaust clamps and rear mounts. Let the mufflers seek a natural position as you tighten the rear mounts, then snug up the clamps.
Back in the day, others loosened the engine mounts, tighten left side first, on the right side there are pinch bolts, loosen those, tighten the right side and then the pinch bolts. These then seek a natural position... likely not a lot of benefit, but maybe. If the dealer doing the recall followed the complete engine mount bolt procedure to the letter, this is already done.
Proper throttle body sync will help, but even better if all your valve clearances are uniform, being totally anal about it.
