People run the NF Payette in "creek" boats all the time just like Big Timber gets run in "river runners". If you want to avoid overlap get a dedicated play boat, or a squirt boat.
From the OP: "I’m looking for a fun, fast river runner with edges ..."
I gotta' agree with Montuckyhuck - this seems like a rather strange conversation. A Burn is "responsive"??? I have a Burn and love it, but it's my creeker, and by far the _least_ responsive of all of the 7 (yes, seven) boats in our family.
Before you get yet another high volume boat, borrow or rent something that's really different. For what you're talking about, I love the RPM. It's an old design, but there's a reason that it's the best-selling boat ever produced. It's very fast, doesn't pearl when surfing (the Diesel is terrible for this!), has real rails, and you can really carve with the sharp chines on the stern. My wife (~110 lbs) and I (150 lbs) both fit and like it. There are of course much newer designs that are planning or semi-planning. The RPM is a displacement hull, which you may or may not like, but despite what anyone else says, displacement hulls are _fast_. Displacement hull boats don't spin, but you'll catch waves that everyone else blows by.
Depending on how much you paddle, you might want to stick with a planning hull. Planning and displacement hulls usually have quite different feels, and the secondary stability characteristics are also usually very different. The choice of boat also depends a bit on where you want to go. E.g., highly asymmetrical boats (like the RPM) are more difficult to control when side-surfing. If you aspire to do rodeo moves, then you'll want a boat that supports those. If you're mostly surfing, get a boat that surfs well (this is most decidedly NOT a Diesel or Burn!).
Regardless, it really seems like you want a much higher performance river runner, or maybe even a play boat, before you get yet another slow, high-volume boat. I could go on about this, but you really need to try a few more boats and see what you like. Sounds like you'll be happier with Fun Runner, Axiom, RPM, Remix, or similar. See if you can borrow a some different designs, even if it's only for a few quick surfs or ferrys during a lunch break. There are many older designs that are excellent all-round boats - way higher performance and much more fun than a Hero, Burn, Mamba or the like. And with a bit of experience, any of these are fine for Cl 3 an 4.
