yes, without a sidechain.
bitcoin sidechains are useless IMO

correction, a much much slower wheel
With much higher access to cash.
For those interested in the technical aspects, here I've found a good explanation of the sidechain concept:

Yes, we could do it trivially via the following process:
1. Define a multi-sig group on the bitcoin network as the highest N witnesses
2. Transfer funds to that multi-sig address and have the witnesses issue an asset in return
3. Have funds sent to the witnesses direct them to a bitcoin address to withdraw to.
The primary challenge is implementing the communication protocol for the witnesses to approve the deposit / withdraw.
