If you could base this purely on Ether then imagine what would happen to ether prices? They will skyrocket even further - that would increase the value of funds raised. This will generate more hype and more interest.
That in turn would benefit the whole ether ecosystem.
It would be good if you could wait until some of the other ICOs are over and people can cash out first. I'm all out of investment funds until then.
Our goal is to support Eth and BTC (and other popular blockchains such as Lisk in future), enabling true multi-blockchain DAO's via Wings.
We are quite aware of a certain ICO/DAO "fatigue" lately, and are actively discussing the best date to schedule the Wings DAO.
Moreover, the Wings DAO will only start after we have the white-paper, prototype / testnet up and running and other tools and materials.
