Please allow me to attempt a part of your qn. From your list, I only have experience with Waterman Phileas and Pelikan M800 series. Ink-wise, I only have experience with the Iroshizuku, Diamine, and Pelikan 4001 Royal Blue.
I have no idea how far the tines are apart in your pens: every pen is different, even from the factory. And the difference gets more pronounced with writing.
Some pens support being super wet and have the potential to be a gusher. While some pens, even with tines opened, will not put as much ink onto paper as some people might desire. This has got to do with the nib grind and feed, and probably convertor.
As for ink, some inks flow freely and fast; while others are more reticent, stay closer to the nib, reveal the nib grind. Another point is how the ink reacts with paper. E.g. Some slower flowing inks may pentrate the paper very quickly, others may form a barrier and not penetrate the paper thoroughly. Same for faster flowing inks.
For me, Pen-ink combination is a matter of personal taste. But please do not discount another factor which is paper. So, Pen-ink-paper. and for me, pen-ink-paper-hand-weather. at least 5 variables in this game. and this can be a huge permutation.
I am sorry you did not get specific answers from my blabber.
I can imagine Pelikan M800 with unadjusted tines "doing well" (no feathering, no bleedthrough, and legible enough. Sheen and shading is another matter) with 4001 Royal Blue on absorbent papers. If adjusted for wetness, on Rhodia, I can imagine some shading with Diamine Mediterranean Blue. If unadjusted, unprimed feed, it might turn out a tad light. Same for Phileas on Rhodia and Iroshizuku Ama Iro. But this is merely a guess. Please, have fun!
