Not really. Each card would only get 8 lanes. Then no more then two NVME drives will work in the storage card and that only if the board has bifurcation support.

For PCI-E 3.0 i can recommend a card with a Broadcom PEX 8724 controller. Works well with 4 drives and is not much more expensive. The fan is horrible: https://www.aliexpress.com/item/1005001782779648.html

Not sure why this is downvoted. Almost all (if not all?) consumer motherboards will drop the 2 x16 slots to x8 mode if you insert anything in the second slot. So using a PCIe riser for NVME SSDs means your GPU will get less bandwidth. This may or may not be noticeable, if you are running PCIe 4 the x8 will definitely not bottleneck the GPU, but x8 PICe 3 lanes probably will, especially for cards with less VRAM.
