capping "uneven ends" of enclosed surface

[2ms1]

Can anyone give me suggestions on what the simplest way
of turning this thing into a solid would be?

If it had smooth ends then I could just use "Fill" with a
couple sketches where I "use edge" to draw an endcap for
each end and then use "Solidify".

But when they are uneven like this there is no plane that
intersects the entire perimeter of each end. So I can't
use "Fill".

I suppose I could try to make 4 chains out of each end
and use boundary blend, or something like that. But it
seems like there's gotta be a more straightforward way of
just getting this thing into solid form. I could trim
them down with datum planes and use "Fill" (or
equivalently create planar surface and "merge" leaving
out the rough ends) and that's probably what I'd
otherwise do. But I was curious if you guys had any
other suggestions for me. I feel like I'm missing a lot
when it comes to surface modeling strategies.

I realize the ends being "rough" means the shape of any
"endcap" would not be well-defined and that's fine with
me. I guess I'm basically just wondering if there's
anything that's even more "quick and dirty".

Quick and easy way?
Create a point somewhere in the center of your "circular"
geometry, maybe outboard from the edge. Then create a
boundary blend using the perimeter edge as one chain in the
first direction, and the point as the second reference in
the first direction. You could define a plane through the
point for tangency control as well.

Wow, I would have never known you could use a datum point
as a "curve" to create a boundary blend like that. But it
wored like charm.
