Using cryptos as alternative pledge method on Kickstarter?

Hi Steemit, I need some advice.

I'm planning a Kickstarter campaign for a videogame we're developing. Since my last campaign over 2 years ago, I've noticed projects are using Paypal as an alternative method to pledge, for people who don't have credit card/don't like paying via Amazon or whatever Kickstarter is using today.
So I'm wondering, is anyone doing the same with cryptocurrencies? Could we offer a way to pay via Bitcoin? (or I'm thinking something more usable like ltc, dash, doge, pivx, etc). I guess we could stick an address to send payments to on the page, but we also need to collect a private message from the person, like what reward they want, their address, etc. Is this possible? maybe with some widget that can be embedded in the KS page?

Thanks.
