I'd like to see this port get some traction.  Presently on Current LXQt 2.0, 
you can't bring in any icons other than breeze for a dark theme.

One potential pitfall with the submission is the incorrect format.

This link is a little out of date:

https://www.openbsd.org/faq/ports/guide.html#:~:text=Submit%20the%20port.,encoded%20to%20the%20same%20address.

In addition to inline mime encoded in the body of the email, the mailing list 
will now accept the patch, as a *diff, as an attachment.  The  mailing list 
will display the attached diff but not a compressed, archive file.

To create a diff:
https://www.openbsd.org/anoncvs.html

Rafael Sadows is all things Qt5/6 and has a full plate.  Getting him to review 
your *.diff would go a long way.  I think he has commit privileges.
