Help finding a stand that will support two monitors above a 34" 21:9 monitor

[Things change I've changed]

Hello I'm trying to find a monitor arm/stand that will allow me to have two small 22" monitors mounted above my 34" 21:9 monitor, I'm finding it hard to find something that will work well, if anyone could help it would be greatly appreciated.

I've found this but I'm wondering if it would go high enough,
