minning rig

My cpu has 16 pcie lanes limit and my mother board has 6 pcie x1 slots and i have mounted 6 gpus using pcie risers.yesterday I saw this 1 to 4 converter for risers and now I'm hoping if i can use this converter to mount more than 6 gpus Cuz they only use pcie x1 and 1 pcie lane =1 pciex1 slot...
