None of those are c-41; they're all regular black and white. Unfortunately, Delta really isnt my thing (I prefer HP5+ and FP4+), so I have no interest in them (Not saying they're bad; they're pretty damned good. I just have my process down for HP5 and FP4 and have no reason or desire to switch).

What's keeping you from getting a tank and the chemistry to develop black and white film? Right now, I'm developing b&w negs normally and also reversal processing them as slides in my bathroom with no trouble (Though I am converting an old storage shed in the backyard in to a darkroom). ATM, I do send my film off to get scanned and printed, but I do the processing myself
