First off different gentic modifications were used between the Orion Project (Aka Spartan I program) and the Spartan Program under Dr.Halsey. And additionally for the subsequent programs. Spartan IIs, IIIs and IVs do not create Spartan 1.1s when they procreate, and Spartan IIs can't procreate anyway.

Regarding their technology it wouldn't matter. They would be wiped out to fast to bridge the technological gap between them and the Imperium. I know you don't want to hear this, but the UNSC does not stand a chnace against the Imperium in an all out war. The facts are painfully clear.
