Anybody running a frame on a thundercloud?

Hello, I currently have the opportunity to get a pretty good deal on a thundercloud and I’m wondering if anybody can share their thoughts on running a frame on it? I will only be using the raft as transport to fishing spots along a wide class I/II river and I will not be fishing from the raft. My hope is that a small frame can be used and the front thwart can remain intact and used by a passenger. Any pictures or anecdotes would be appreciated.
