You can do that, but you would have a whole (missing) section of the Spark tables that could not be optimized, past 0.92 g/cyl. If any KR is generated in that range, you could not tell exactly at what boost level it occurred.
If no KR is detected, and acceptable WOT power is achieved with the limited stock timing table, of course that's workable.
But I think you'd be leaving some performance on the "table" haha, pun intended
