It would be different but I don't know if I want that.
That seems to suit ODST's more as they need to be tactical. For me playing as a Spartan means you're a super soldier, running into battle not hanging back giving orders. It could slow down the gameplay and I think a Spartan based game needs to be fast and action packed.
Or it could be after finding first Ghost recon slow and more of a chore it's tainting my view of what you're suggesting.
