What I'm looking for is some type of ball and socket bracket that would
allow side to side motion without transmitting the stress to the screws.
I think you'd end up with a very floppy bimini.
The type of brackets you have allow the bimini to be lowered (folded up
when
underway).
They are not supposed to hold it rigid. That's what the straps are for.

Agree. But the straps prevent forward and backward motion. It's rock solid
that way. If there were straps going from the top right to the bottom left
and vice versa, then the swaying motion would be stopped also, or at least
most of it. But, walking around would be a pain.
It looks like a combination of this:

may do the job.
Maybe I don't understand your concept. What you have pictured is a ball and
socket type of fitting that is *designed* to allow it to flop around. If
your idea is to tighten up on the socket so it clamps down hard on the ball
it might stiffen it up *however* all the forces due to wind, etc. will
still be imparted on the bracket screws. You mentioned they are screws,
not bolts with backing plates. IMO, you're going up with cracks in the
gunnels.
Too stiff is not always good. Wait, let me rephrase that.
It's not always desirable to mount something like a wind catching bimini in
a manner that it can't "give" a bit. All the forces will be transmitted to
the brackets. The straps provide *additional* fore and aft support, taking
much of the stress off the brackets. They are there with consideration that
you may have the bimini up while underway.
That's my opinion.
