Slide profile in Lightroom

I have "thousands" family and relatives slides that I want to digitalize, as I don't have the time to use a scanner I've set up a slide duplicator with a 5dMII tethered to lightroom. It works fantastic and it's very fast, I just have to crop images, apply a preset, small retouches and jpg export. The quality is more than enough for my needs. The problem is that when I'm scanning I usually create some profiles with Lprof and Wolf Faust It.8 slides and apply them in photoshop. This of course goes fine and photos improve a lot, but now that I'm using lightroom I would like to keep inside the program because that would speed up the process a lot. So far I'm shooting at a "kind of" daylight bulb and applying a modified "Faithful camera" profile. This puts me pretty close. Things I've considered:

- Using dng profile editor and manually adjust patches of the IT8 slide: A part from being time consuming there isn't a way to see output numbers in dng editor so this option is out of question.

- Using Rags IT8 script to create an ACR/Lightroom camera calibration preset. I don't like this kind of calibration but even so I would also need a lot of time to adapt the script to Wolf Faust numbers specific numbers.

- In the Adobe web I found that there are no "camera profiles" built by third-party software. So my guess is that there isn't any way to convert an icc to "camera profile". Or is there any? That would be the perfect solution.

A part from this, another problem I found is that a lot of slides are 80's with faded colors and I think there isn't a way to correct individual rgb channels in Lightroom. HSL sliders work sometimes but they are far from perfect. I know this software was not made for this kind of works but mabe someone has found a workaround.

Any help would be appreciated.
