Considering Northstar Firebird pack

29 lovely pounds

I also did it to my Northwind solo. I am 6'4" with long torso so it significantly lowers the center of gravity

I don't know if this is anything you'd consider, but any solo with lowish sides can be converted to a pack style canoe.
I'm currently converting my North Wind solo.
You can order all the parts necessary from Northstar.
One of the advantages to doing it yourself is you can adjust the seat height by adding layers of minicell under it.
I'm also making mine adjustable, fore and aft, by sticking strips of Velcro to the bottom of the canoe and the bottom of the foam seat.

Well, I did get the Firebird pack and had a great season with it. Never really thought much about converting anything since I don't have alot in the way of work space and good used canoes around here have been in pretty tight supply.
The Firebird got me exploring some great little streams last year.
