ICO question (technical)

[btc4peace]

Is it possible to create 100,000 tokens and sell them for, lets say $1 and the value of the tokens is then calculated by the value of the master wallet ÷ 100,000?   

The tokens could be traded on exchanges still but the core value based on wallet balance.

I could just calculate it for display but that doesnt really guarantee the funds are tied to the tokens since one could simply withdraw funds.  The idea I have is neato.   

I am considering ETH and Waves.
