I foresee two potential issues:

1. Your hops would be sitting at fermentation temperature for a couple weeks. Not ideal but maybe not a deal-breaker.

2. A slow trickle of CO2 leaves plenty of time for diffusion to homogenize the gases in the receiving keg. Fermentation produces ~20 vol CO2, so if the keg started out full of air (~20% O2), the end result, at least theoretically, would be a keg with ~1% O2 content.

damn

You may have better luck fully purging the keg with sanitzer first by fully filling, then pushing it out. Then pop the bail and add your dry hops.
Then you could attach your line from your fermenter to purge out any introduced O2 from adding the dry hops. May get you a bit closer to lower levels desired.

I have had good luck with spunding in the keg on top of the dry hops with residual extract remaining. The active yeast mop up any available O2 pretty quickly and leave you with that fresh dry hopped nose. Just a thought...

Yep, I'm pretty happy with the final product using this approach.

I just tried it for the first time this week (not spunding but adding dry hops to the primary while fermentation was still active, though winding down).

I added them on day 4.  I was hoping to keg on day 8, but I was busy and didn't get around to it.  I'm hoping to get it kegged up tomorrow night (day 12).
Be excellent to each other

Denny,  how do you like the results of dry hopping with cryo-hops, and are you using half your normal amount of pellet hops for it?
I am a great believer in luck, and I find the harder I work, the more I have of it.

I like it a lot and I use about the same amount as I would with regular pellets.

Decided to dry hop the keg (1st time I've tried this). 1st few beers after dropping the hops in were a tad hazy...then the CO2 tank went flat. The HBS here in Denver said to go to the Hydroponics store to get CO2. Wow...there's more pot growing stores here than beer brewing stores...great $10 exchange at the Hydro store down the street...the beer is running clear and hoppy...

A question for the people who sink the hop bag to the bottom of the keg.  I have done this several times and the result is the first 3-4 pints are super hoppy.  Then suddenly the rest of the keg isn't super hoppy even on the same day.  So I switched to free floating bags that eventually sink.  The result is hop aroma is more homogeneous throughout the entire keg. 

I guess my question is how can you sink the hops from the beginning and not experience the same thing I have?

To be clear, the reason I sink the bag now is to keep it away from the Clear Beer float which draws from the top.

That makes sense.
