I would say no.
The easiest way to bottle, in my experience so far is to rack to an empty keg with your priming sugar already in it and purged with co2. Seal it and purge again then shake to distribute the sugar and push to bottle with a couple psi of co2.
however, in terms of minimizing losses on a small batch, if you can avoid disturbing the trub it's probably a great way to go.
Again, you've got the extra vessel (the keg) to clean and sanitize. Plus hoses and such to deal with. So, to easier using a keg as a bottling bucket, I would say no.
If you're using a keg to carbonate your beer, again not easier but you get no (or very little) yeast sediment in the bottle. A desirable outcome.
But, you have to BUY the keg (or several)
And a CO2 tank
And a regulator
And hoses and connecters
And a beer gun or such
And a fridge to cool the kegs.
What are we talking about here, if bought new?...$400?, $800?
I've got a brewing tool that I assembled for $4.75. Even if you already have all the kegging stuff, I think this may be a tool you will want to have in your brew cabinet.
Give me a couple weeks to get some results and I'll post a "how to" new topic thread with pictures.
