I can make it give 2 more nades per pickup, but I don't really think that will make much of a difference. I think 8 is enough per pickup. The respawn time I can't really change without a workaround though. There's a couple of 'types' of pickups, which define the respawn time (For example, the difference between a health pickup in LS and the one in FC/WV). But, I don't really think the grenade spawn needs much change. If you want a lot of nades, you'll just have to stick around a bit longer.
