Any happy darkroomer doing black and while film reversal process?

It can be done, but is it good? 
if you are a happy darkroomer, please advise what film do you use, what developer, what any tricks, Thsnks.

Haven't done it myself, but I do know FOMA has reversal film and chemistry.  I can't recall any others.  Or, perhaps you're looking for a roll-your-own alternative?

I remembered Tmax series can be used for reversal, can’t remember what chemistry. My impression almost any B&W film can do it. 
Never tried it. Now it seems only limited film are suitable. 
 

I like a lot the image of Kodak B&W movie film. I think it is copied to make the projection film. 
 

I want to make some B&W slides for projection, particularly want the 54x24 panoramic projected through 6x6 medium format slide projector.  Would like to know what to expect before step into the water. 
 

The camera would be Hasselblad with DIY 135 to 120 roll form adapter. I have a lot of old Gepe 54x24 plastic slide mount.

That sounds fairly awesome.  We still enjoy "shining pictures on the wall" as my kids used to say.  Although that was all E6.  I think you are correct about most any B&W film can work, it's more about the chemistry in the development.  I suppose the "reversal" films are optimized for that process, but I remember 'regular' film could be used as well.  This is something I have had in the back or my mind, to try one day.  I encourage you to give it a go, and report back to the forum, good luck.

Recently, my “shining pictures on the wall”  are through a 4K 85” TV, but last week I took out 6x6 slide projector, it appeared something different that I haven’t enjoyed for a long time. Not sure what it is. For once I thought it was the color depth, but TV should be better, or maybe the resolution? Still No. or maybe the color gradation? Anyway, …

There are folk on the internet who have developed a chemical-only method to avoid the 2nd exposure referenced by Ilford.

I have no tricks to offer but Adox Scala 50 is made (according to Adox) for the reversal process. Take that with a pinch of salt because Adox HR-50 is the same film, so I guess Adox realised pigeonholing a film as a one trick pony wasn't aiding sales. HR-50 is an excellent film anyway if you can't get it boxed as Scala, and Adox do a reversal kit but it seems difficult to get unless you are in Europe.

I did this a lot in the 1990ties. Even did a stereoscopic slideshow with B&W slides.
You can do it with any B&W film. Used at least PAN-F and Fuji Neopan 400 for it, but may be some more I didn't recall now.
But in these days there was no films with clear base. All films had a gray base, except the Agfa B&W slide-film Dia Direct with 32 ASA, that was still available in these days. But the the Dia Direct came with processing, so no need to do this on your own. But it was too expensive for me, as a student. Agfa Scala came years later.
Because of the gray base the slides came out rather dark in a projection. You can't mix it up with color-slides. Today there are lot's of B&W films with clear base. I would prefer them for slides.

I mixed up the chemistry on my own, using the ORWO recipes (ORWO 829 first developer). In all the classic processes they use bichromate in the bleach, what is forbidden now. That  worked perfectly. In today sets they use potassium permanganate instead. With that I always had problems. It softened the emulsion very much. Hopefully todays films are hardened enough to withstand, but I don't know.
