Thanks for the input Jnanian, very valuable information.
I've been having my brain on the back-burner all day (working "off-line" on the problem, while I was doing other stuff), trying to figure our how to successfully do this.
From the scraps of information, the ParkerHarrison's used paint to mask their clip-ins when they merged and manipulated, and they also painted the final prints (as far as I understand, the prints in the series are pretty huge and impressive).
You can see most of their works from that series here:

- Very impressive and etheral'ish feel, also sort of a steam-punk-style to the technology the brother uses. =)
Love the mood and the message, processing....well just about everything. ^^
I have tried to develop a few prints in caffenol (C-H), it seemed to be pretty low in contrast though, but then again, the prints I tried in caffenol, ironically concerning this thread, was actually taken on a foggy day, haha!
I blogged about it here:

The paper I used for that was "Work", fixed grade 3 paper (RC), something I got with the enlarger i bought used...it's more brown than green really, but it is kind of green
I've been thinking if I should just try and scrape off or dissolve the first paper-positive's paper-emulsion with something (terpentine???) at the horison level.
If I am able to have control while dissolving it somehow, it will most likely give me pretty smooth transitions, then I can use charcoal on the back of the first positive, to "dirten up" the haze, while still looking smooth, along with dodge/burn on later stages.
I indeed need to tone the print, so the caffenol-tip was a good one =)
