This is Vne diagram which addresses banked turns +, negative G limits - axis, AoA loads +up 7.5G, and Q load limits resectively for 120IAS kts to 270kts Indicated at 30000 feet through 425IAS (kts) at 10,000 feet

This diagram works for all increased loads for Bank, Pullout (AoA load) and Dive Q limits for Limit Load of 7.5G design.
 
Thanks Bill, once explained the light bulb came on!
 
The important thing you'd have to factor in is the position & compressibility errors, but if I was to ignore that, I could provide some baseline estimates for the maximum mach number that could be achieved at high altitude.

Altitude_____IAS_________TAS_________Mach
10000'______422.5________491.5________0.770
15000'______388-389______489-490_____0.781-0.782
20000'______356__________488_________0.794
25000'______318__________475_________0.789
30000'______271-272______443-445_____0.752
