You can use the top 4 strings from a 6-string set of Thomastik-Infeld Acousticores:
(you can buy single strings here:

And then use the top string from the LaBella Nylon-Core Piccolo set. It's meant to be tuned up to G, but it works just fine tuned down a full step:
(
http://www.juststrings.com/lab-abn70bb.html - you'll have to buy the full set, though you might try using some of the other strings if you like the gauges better).
So that would get you these gauges:
A = .068
D = .053
G = .041
C = .035
F = .022
Those are the top 5 strings I'm using on my 6-string Kinal ABG. Though I've got them tuned down a minor 3rd most of the time.
