The closest thing we have to what you're looking for is the Timing CPU model, which models a 1CPI in-order CPU, very basic, but models latencies from the memory system. Any stats you changed/added within the O3 CPU would not be transferred by using the Timing model, but any stats from outside of the CPU (like in the memory system), would still be there.
