Well, I suppose you could try the old-fashioned way. Create a new image
the correct size in the graphics program of your choice. Add the icicles
image as one layer, add the trees as a layer behind it, and see if
painting the areas you don't want in each image as transparent. That
would eliminate algorithmic guessing at control points. Then try flatten
and export it...
Similar to what could be done with Hugin masks, I think. But the focus
in each image is quite far apart from the other, I think it would be
tough either way.

Thank you so much for trying to make this work. I've had a couple of
crises pop up the last few days and haven't been able to respond.
I think the lesson I learned is there are limits on what this tool can
work with. There are really no sharp point on the near image other
than the roof and there are certainly no sharp points on both images.
Further, the snow around the trees makes it impossible to figure out
what is in focus on the far image and I suspect that's why the
ghosting around the trees shows up.

Thanks. I was looking at that again and the close image really
stands on its own. I think the combined image might be too

What I've managed to produce so far is too cluttered. The massed
detail of the trees overpowers the icicles.
That said, I'm still trying to figure out how to use this tool.
The images seem to be projected onto a sphere, then aligned, and
then projected back to a plane. That makes sense if the images
are part of a panorama but these images are mostly on top of each
other and I had to do a bunch of roll, yaw, and pitch of the
resulting image and I have no idea why.
First time, I tried using Hugin's align image stack function. That
failed with an error. I think the focus in the two images is so
far apart it can't find any control points between the two.
Second time, I loaded the images, went to the GL preview window,
and ran the Assistant. It gave me an image with the icicles very
sharp and the trees all blurry (because that's how they are in the
close image), even using the Exposure fused from stacks output.
Third time, I gave the far image a second lens, ran the various
alignment steps, and came up with - an image much like what I got
the second time.
The fourth time, I added a mask to the close image, drawing one to
include the biggest of the icicles. That produced an image with
that icicle sharp, and nothing else improved over the previous
images. While you could go through and mask everything you want
included in each image (icicles from close, trees from far)...
that's a lot of work and I'm not sure it would produce anything
like what you want.
Fifth time, I removed the mask and set Hugin to output remapped
images. Then I fed them to enfuse using a command line based on
what I found at this URL:
https://macrocam.blogspot.com/2013/09/using-hugin-for-focus-stacking.html
That produced an image combining the focused trees with the
focused icicles. Well, the icicles are sort of focused. There's an
odd, ghost-like sort of look to them, like enfuse sort of fused
the in-focus icicles with their out of focus versions. But it's
enough to reinforce the likelihood that an image combining the two
would be cluttered and crowded.
So I think it /could/ be done, I don't think it should be done.
The close image looks to me like a much stronger image than the
far image. In the far image, the icicles just look like mistakes,
that you were trying to get a picture of the sun-lit trees, and
the icicles are just in the way.
I think this is one case where doing an actual painting combining
the two images could make it work, but even then it might look
cluttered.
The focus stacking might work better if you have more focus layers
than just two. Perhaps images with the two dark stumps in the snow
are in focus? Well, maybe not. I see they are in focus in the far
image, while the trees themselves aren't as sharp.
Maybe you could try it with a pinhole could come up with enough
depth of field to get it all in focus?
