As well - no.
You may think about Agfa Copex Rapid. It is a reproduction film for grey tone reproduction. It is quite sharp, and gives with SPUR developer fine shadings of grey. It can be used even on sunny days. But the resolution is lower. I made some prints from 35mm -> 30x40cm. I burned in the sky slightly, and got some grain there. Agfa High Definition Pan is nearly grain free. You may have problems using a focus scope - you don't find any grain.
> a good compensating developer like DiXactol if you are using 120, or 510 Pyro,
No way. I tried everything. If you use extremely diluted compensation developer you may prevent the film building up to much density. But the "medium density" is the same across the whole negative, much to less differentiation. SPUR developer contains a forceful inhibition system, whose effect cannot be copied with other substances.
