Unable to upload to Snap Store because of too many layouts

I have a working snap that I’m trying to upload to the snap store. My snap uses the apertium package which puts a bunch of binaries it needs in /usr/bin. To make the snap work I included layouts to link to all of these binaries, and it crashes without these layouts:

This works fine on my local machine and I’m able to install and use the snap. However, when I try to upload to the Snap Store I get this error:

Error while processing...
The store was unable to accept this snap.
  - too many defined layouts (36 > 30)

I’ve tried different things to try to fix this like messing with using bind instead of symlink, and using a layout on the entire /usr/bin directory but nothing works. Any suggestions?

For reference there was a discussion on this topic a while back here: Why are snap layouts limited to 15 entries?

I suspect you can remove all the layout definitions and adjust your code on line 36 of translate.py. Don’t use echo | apertium, instead call apertium directly and push the input into the app’s STDIN pipe from your python code without the indirection of using echo.

If I replace the line:
return os.popen('echo \'' + input_text + '\' | apertium ' + from_code + '-' + to_code + '').read()
with:
return os.system('apertium ' + from_code + '-' + to_code)

then I still get this error when the layouts are removed:
/snap/argos-translate/x1/usr/bin/apertium: line 641: /usr/bin/apertium-destxt: No such file or directory
/snap/argos-translate/x1/usr/bin/apertium: line 659: /usr/bin/apertium-retxt: No such file or directory
