PCIe A and E key splitter device
In theory, it's possible to build a card featuring a MUX chip for the PCIe lane, separating it into another A+E slot for the Wi-Fi card and a riser for the GPU. However, such an approach would likely be more expensive than the value of laptops where this upgrade could be useful. Your GPU is confined to a shared PCIe 2.0 lane, which significantly limits performance—though a 3.0 mux might exist, its cost would be prohibitive. The riser remains attached to your laptop, posing mobility issues. Internally, the wiring could clash with the MUX chip due to compatibility constraints like BARspace and PCIe device limits. Most importantly, no one seems motivated enough to invest 300 dollars in a solution that keeps a weak GPU in an outdated laptop, so such features are unlikely to appear. Your best option remains using the A+E key for the PCIe slot, connecting a crypto miner MUX card with dual PCIe ports, an A+E adapter on one side, and the GPU on the other. Hopefully, everything will function smoothly.
