Scenario "A" won't work because Photoshop is smart enough to realize
that the source/destination are the same profile. You'll get a "null"
transform. Besides, a profile-to-profile conversion will only work if
you don't care what happens to the "purity" of the colors. For
example, even if both source/destination are the same
"colorimetrically" (both profiles created from same data set), it will
still re-separate the image (K-only areas like drop shadows will
become a CMYK build). AFAIK, device link profiles are the only way to
prevent these sort of things from happening.
You've got GMG Colorproof, don't you Roger? Have you thought about
adding a ColorServer license to your GMG RIP?
Also, if you're looking for a "Photoshop" solution just for image
conversions, you could get the Alwan device link plug-ins to do the
conversion and then get either Alwan Linkprofiler or Left Dakota's
Link-o-Lator to build the device link itself. Be forewarned that the
Alwan plug-ins currently only work with Photoshop CS2. No word on
whether they will update them for CS3.

Let's consider two hypotetical scenarios :
• Scenario A) bring down the TIL to 300%
• Scenario B) bring down the TIL to 270%
In Scenario A, would I simply convert from SWOPv2 to SWOPv2? For sure
whathever that was 340% in the Source is going to get squashed to
300% by
virtue of SWOPv2 being limited to 300% in the Lab to CMYK direction.
