Upgrades will never be available for credits and we already have an award which is purchasable for credits.
The only think I can think about is to either add something like a "prestige", which you can buy for credits. (1st prestige 200 credits, 2nd 500 credits, 3rd 1500 credits, etc)
or a virtual stock market.
