multiple xs716t switches aggregate uplinks to router?

hi,

need some answers to an uplink questions of xs716t switch.

would like to use two xs716t to provide redundency to end devices therefore they are connected to exchange information and settings,

furthermore, each of the two xs716t provide a link as redundent uplinks to an edge router/firewall.

the topology is shown in figure attached.

i wanna know is it doable to bind the two uplinks from two xs716t respectively  for redundency and double-throughput ???

thanks~~!!
