Hi Steven,
There's nothing wrong with your point of view. The Ceriatone OTS is tweaked at a point it also sounds good without the Klein.
If you're concerned at keeping that tone maybe the Line selector from Boss might be helpfull;

Recently I'm on a completely different track with the OTS. I'm modding my amp to a lot brighter puppy and is unusable without my percolator(dlator). More the #124 way but with high plate resistors.
My homemade dlator is about 200 euro costs in parts and 12-16 hours building time. I can't do without it.
If Nik ever decides to sell he probably can do it cheaper...
Grab some coffee with me next friday?
LOL no. I allready own a good espresso machine.
Seriously. I think the tube version is probably a whole lot better. but a fairly pricy option. (i'm avoiding the word expensive)
But do you need a fx loop to:
a. hook up fx?
b. alter your tone?
c. a bit of both?
if it's mostly option a., my " trick" would work. Lees weight. less cables less alteratiin of tone (only when I use the leslie)
