I generally have a problem with drilling into critical components when there are other methods... even if it'll save you 10 minutes per bushing when you relube in the future. With a good PTFE based lube you probably won't need to relube more than 2 to 3 times a year (if that)... do it when you change your oil and inspect your suspension. You can always get crazy with the drill later if you still feel the need. BTW, I've heard some reports that powdered lubes like graphite work quite well too, but I'd try a drying PTFE based lube first.
