No pun intended, but you are embarking upon a slippery slope.

Please leave Bitcoin the way it is- we don't need no stinkin' 10% annual inflation. To put it into perspective the US dollar currently inflates at around 1% annually.. 10% is just a ridiculous number.

Also this would leave many ASIC companies and purchasers with useless equipment and there would be some blow back suffered from the harm this would do to the way people trust Bitcoin. When you change the rules as you go, people may not be so apt to invest in Bitcoin. The rules were written a long time ago and everyone here has accepted Bitcoin how it is today, why change it now? It would only lead to a loss of confidence.. in today's troubled market this would be very bad.
