'99 front end swap with '02 Parts?

Hope this forum hasn't coved this yet (if so, sorry). But I just bought a 1999 Silverado Z71 and though I like it's styling very much, I like the '02's more agressive grill/hood a little more.

Does anyone know if I could swap out the hood and grill on my '99 truck for an '02 without changing the rad. support, quarters, headlights, major grafting, etc...

Thanks in advance.
