Sounds like you're straddling a pretty high fence.
An R-2 boat like a Shredder or Jack's Culebra is pretty specialized, for thrills and paddle power. Likewise, a Mini-Me. You can fit them with a frame and do multi-day trips, but they aren't really designed to rig gear efficiently.
A friend is bringing her Shredder out next week— we'll try to come up with a reasonable frame for it, and I'll post the pix, if they're worthwhile.
Meanwhile, you might want to consider a small cat, like a Jack's Cutthroat or a Hyside. You can rig it with a trampoline floor for R-2+ or put oarstands and a seat on the frame for multi-day trips.
These are Jack's Cutthroat custom tubes (jpwinc.com, 4 dee-rings per side) with my own frame. It's a great solo playboat, too. With no load, it handles like a Mini Cooper. But I can get enough gear for multi-day trips and ultra-light kayak support (and rescue, if somebody gets thumped).
Your choice should depend on what sort of runs you'll be doing most often, or would like to.
Probably no bad choice, except waiting too long.
