Well, just tried it, and Nuhn is soloable as rdm. Probably need W. Legs to do it though. Basically just bio and poison and run, took almost 3 hours, with very conservative nuking. If you pull it down a little bit and outside of the cave area, there's a nice little path you can kite it around that it has lots of trouble pathing through. It definitely doesn't have Regain, so I only have to deal with 10 or so TP moves, which were all either Gnash or Deathgnash. Successfully ran away from them all except for 1 Deathgnash, which, oddly hit me for only 354 damage...stoneskin wasn't even up.
There's a Jnun kind of close to the kite area but it won't aggro unless you have low HP. I aggroed it once after converting and not curing myself all the way, but I just kited it and Nuhn and it lost aggro. Here's a crapp picture in paint of the general kite path.

The red dot is where you pop it. The bluish line is where you pull it too (you'll probably have to kill the 2 imps out there). The brown dot is the rock that you can circle around, and the red line is the path you should kite it in. (Sorry it's so small, but you should be able to see.) (Also there is a small tunnel with an iron gate that isn't shown on this map, that's why the path appears to go off.)
Anyway, only snapped 1 picture at the end of the drops, mostly because I solo on PS2 and sit my char somewhere on PC (to collect the drops).

So yeah, took ridiculously long, but I got what I wanted so I'm happy, and maybe it can help someone else.
By the way, good gear is DEFINITELY not required for this (except maybe w. legs), because my solo char (Angelofchaos) is completely stripped, except for rare/ex gear.
