It might be tempting to drill a few holes into the middle of the spokes, and consider that the hole only removes 5% of the metal, so 95% of the strength is left. However, no matter how small a round hole is, the local strain at the edge is 3 times the average, which is too often enough to start a fatigue crack. (That's what took the De Havilland Comet out, opening an opportunity for the Boeing 707 to found an industry. Luckily, the seminal 707 shape got better mileage.)
