Hi, Sean!
A few comments...
First, there are no seiken thrusts in the Fuzhou Suparinpei that I learned from Simon Lailey and teach. If you're looking at the tape, you may miss that all those thrusting techniques are shokens. In my mind, that reinforces the idea that this comes from the same neighborhood as the three kata that Kanbun taught, if not "the" suparinpei that Kanbun allegedly saw (source - Uechi Kanei's Kyohon).
But yes, there are many techniques in that form (the sokuto geri, the wrist movements, etc.) that make one wonder what source (direct or indirect) the choreographers of the additional 5 forms used for their non-big-three techniques.
That being said...
The seiken fist (in Kanshiwa) very much is an Okinawa thing. It's similar to me choreographing a kicking form for my own dojo because I lived in Jhoon Rhee land and I wanted my students to understand the techniques that "the competition" used. It's partly a "know thy enemy" thing, and partly a matter of just letting them taste a sampler of other stuff out there to round out the curriculum.
What is also more interesting to me though is the progression from sanchin to seisan to sanseiryu to Fuzhou suparinpei. If we consider that it may have been (or was meant to be) a complete package, then we see a progression to greater and greater "elasticity" of movement from white belt sanchin to functional suparinpei. And please, please note how carefully I stated that. As they say, "all is in sanchin." What this means to me is that you take a form like Fuzhou suparinpei, see what it demands of your body to perform it well, and then go back and see if you can infuse those elements into your sanchin. When I see people like Dana Sheets doing her Nakamatsu-inspired whipping sanchin thrusts, I see that elasticity of movement that my suparinpei demands. I have known people to look at what Dana does and say things like "That's not sanchin!" or even walk away in mid performance after asking Dana to show them how she trains to do her whipping thrust. All I can say is that these folks' minds reflect the white belt rigidity seen in their sanchin performance. Their loss in my book!

That's a damn good question. And I don't have a firm answer.
The bridge katas' greatest asset is that it jumbles the sequences and shows the practitioner that the new sequences work as well. That shows some of the possibilities with kata grammar. But then a creative instructor can take a form like seisan, pull pieces and parts out, re-shuffle some of these pieces, and then drill the class with them. Kata then becomes less religion/storyline and more reference-book/tool. And more is expected of the instructor.
It's also worth mentioning that Kanbun said it took 2 or 3 decades to master the suparinpei he saw in China (source; Gordi Breyette - either from Toyoma sensei or Uechi Kanei's kyohon). With the suparinpei I practice (which may or may not be "the" suparinpei Kanbun saw), I would concur that it takes time. Some of that could be done up front with cross-training in other systems, or drilling bridge kata. That would then impart some talent and ability on the part of the student that they could bring to suparinpei which might help them assimilate and appreciate it faster.
Or...you could just dump all the bridge kata and go straight from sanseiryu to more time on suparinpei.
We don't really know why Kanbun never taught a fourth kata when he allegedly saw one and associated it with "the system" that he was learning and/or synthesizing. As I've said before, he only studied for 10 years, and HE HIMSELF said suparinpei took as long as 3 decades to learn. Maybe with the time he spent in China, he thought he couldn't do it justice. Or maybe he thought it just wasn't necessary, and was comfortable with the 3 forms he knew and taught.
We'll never know for sure.
