XP2 can be developed in B/W chemistry to get excellent results.
I use Rodinal 1+25, 12 min at 68°F, EI of 200...YMMV, of course.
I'll let the scientists respond more authoritatively than I can.
But I would be concerned if the structure of XP-2 includes multiple couplers that respond differently to different parts of the light spectrum.
Changing the development temperature might have an effect on the spectral response of the film.
That may not happen, or it may not matter to you even if you are both developing the film yourself, and sending other rolls to a lab.
Harman only mentions the advantages of its ability to be developed in a commercial lab at the normal C41 temp with no adverse affect on other colour film processing but makes no mention of the effect of using C41 chemicals at less than the standard 100F It's as if it doesn't expect anyone who wants to try it in the C41 process at home to think of room using temperature
However if less than 100F were to create problems you might think that it would at least say something to that effect so does this mean that it is OK to do what Donald proposes or not but Harman has never given it any thought and doesn't even know what if any adverse effects will arise as it has never tried to process it at less than 100F ? The later is unlikely or so I'd have thought
Either way I suspect we may have few, if any, users who have done what Donald is proposing. So he can either be a pioneer and do it or can write to Harman and ask them, just in case that Harman has a definite answer but hasn't made any mention of it in its instructions because it assumed that either users take it to a lab where 100F is the norm or are set up for colour processing at home and will therefore choose 100F because that is the known guaranteed process and is quicker?
Over to you, Donald.

I'd just shoot an email to ilford and get it from the horses mouth , they're quite responsive when I've emailed them.
Lomography - C-41 Development at Room Temperature With Stand Processing and Optional Bleach Bypass for Cool Effects
I love being a lab rat. And I love xpro. C-41 DIY turned me off until now because of the reports that temperature is crucial and temperature management is somewhat problematic when lacking a processor. Well, it turns out that's all irrelevant. Read on to see how you can develop C-41 similar to...www.lomography.com
There is just so much wrong in that article.
Not to mention the horrific colour shifts and other problems in the displayed images.
I guess if you wish to destroy the whole precept behind the design of C41, that's the way to do it.
But if you're going to scan it - it'll work out in post ... lol.
If you're setup with temperature controls for C41 processing, why would you try room temperature other than as an experiment?
Not something to try with any images that are potentially important.
