Hopefully not, as it would be "stupid (tm)".

Anyways: There is a near 100% chance that changes to the system are NOT going to happen, unless you can give very good reasons.
Possible behaviour of miners/sellers etc. is NOT a good reason. Possible number overflows or something like this would be a good reason.

Everyone doing mining/trade/whatever with BTC right now knows what they're up to and signed up for. You want to change this system, to keep people motivated or whatever, but this comes at the much higher expense of people loosing trust in the whole thing ("Wait, they can change the rules?!"). Also to have a different ruleset, you'd need to have a LOT of miners and nodes agree to installing your new implementation...


Long story short:
Not gonna happen.
