I went to Paris and London in 2016 and took only a Panasonic LX-7. I was traveling with my elderly father-in-law, my mentally disabled brother-in-law, my wife, and our two children (16, 11.5). I also had two laptops and multiple kindle fires, usb batteries etc in my carryon. I had no room for more. The images were great and I care share some links to some of the SOOC jpgs here:
Years before I went when my wife and I were pre-children and I took my K100d Super the 50-200 and 18-55. That combo also worked well with the level of gear and time available. In retrospect a faster prime would have been helpful with that old ccd based sensor.

With your gear I’d say if you plan two Pentax DSLR’s KP and K70 plus the 16-85 AND the 18-135 go so both of you have a good wide/standard/telephoto all around zoom. Then the 10-20 if you plan time in cities where the extra wide view would help. On top of this the 35 or 50 prime for lower light use makes for a good option.
The 55-300 is an option you could add to the gear load but the 135 end of the 18-135 is probably long enough.
Alternately take the Q and the zooms and add the KP and the 16-85, 10-20, 35 or 50. The 55-300 could be useful but I don’t know if it would be needed with the Q along.
