You can't have both because if the XM8 hadn't been cancelled there would have been no need for H&K to develop the 416. Both rifles were intended to do the same job; to replace the existing AR-15 based rifles in US Military service with either a totally new system (XM8), or, when that project tanked, with a lower cost alternative that replaced the unreliable operating system with a proven one (HK416).
