Or, if you cap blocksize at 10 M tx, than A needs to sell the exact same amount of CPU and buy the exact same amount of ASICs. Either way, Miner A ends up with the ASIC cost equivalent of 90 M tx worth of CPU in additional hashing advantage over B. The centralization has nothing to do with block size. It has to do with Miner A having more money than Miner B. Alternatively, you might need to add a few more crazy assumptions.
