As Buzbee mentioned "Fuzzy Wuzzy" use the companion way set/douse all the time. For us it started with the guys at X-yachts and Diamond sails convincing us to use this system on the X-102 we got close to 25 years ago and we never turned back.
Some of the advantages are: no need for more than one person forward of the mast, no need to disconnect any lines (we keep them connected for a whole regatta), the crew can stay on the high side (if needed) during sets & douses, no need to re-pack (if it came down it will go back up), less risk of getting tangled with the Genoa, very easy when sailing shorthanded (Marie and I use it often when we sail with the kids) and best of all it is always the same (port side) - less confusing for all involved.
Potential disadvantages:
Prefeeding the foot takes a little longer, somewhat harder to do a gybe set and windward take downs are harder coming in too hot in 20+
We use a deep bag from Layline suspended from Spectra lines each side of the copanion way- this makes it easy to slide it forward or clip it to one side between races.
