I do not know if I would use Rodinal for this. It is more a question of dilution I guess, since you most likely will not get high enough contrast in Rodinal to compensate for the underexposure, especially in 1:50. Even 1:25 is probably not be "powerful" enough to build up contrast. You may have to use 1:10 to get enough alkalinity. Be prepared to get huge grain size and a very nice pictorial look. In general Rodinal is not a developer suitable for pushing. Why don't you try Calbe A49, an old and proven Agfa Atomal formulation with excellent capabilities for pushing (if one has to at all).
