I'm glad you have your plan planned out dan. Wouldn't want you to have your plan unplanned.
Unfortunately, Killing Machine is also a dead end, and his level caps at 50, which really sucks.
And I don't think anyone is saying that KCS->Jamirus->DatA is the easiest way to get DatA. We were just answering a question about Joey Ravn's party and where to go. The easiest way to get DatA is clearly Wailin Weed + Demon family.
I just synthed a coupled high-rank-just-scouted monsters to get an A-rank with a demon to get some of mine.
I don't use them for sything until I've trained them to level 30 or so, then synthed them with a Phoenix Staff, until they have good stats. Doesn't take too long.
But, the one I have, I got by synthing a komodo with something to make a Green Dragon, that with something else to make a... That aquatic dragon... That with something else to make a Red Dragon, then Mechanodragon, then Abyss Diver, then Megalodon (Or whatever it's called), then Dracularge (or Drakulard, I forget which is which) then Great Dragon, then Demon at Arms.
I had it ever since I decided to stop using the Incarnus. Which was right after that Palace island.
As for the Living Statue, It was a Slime, and my starter (a Dracky), going up the ranks of slimes until King Bubbleslime. Then after that, it was a Living Statue, then a Yabby, then a Buffalogre, then a Living Statue.
The Killer Machine is only a 4th Gen. I just got 2 Bodkin archers, 2 Beetle-thingys, synthed them to get, 2 skeleton soldiers, synthed them to get Phantom Swordsman, and synthed that with a Metal Hunter. I didn't train any of them but the Killer Machine rocks.
So, my Zoma will be basically everything I used Early, Mid, and some of Late game.
On a separate note, I got 10 darkonium crystals before going to the last temple, which made that scene funny.
Oh, great, I've been rambling. And stuff... *Snore*
