I would imagine this development method would work fine but it appears to
complicates a fairly simple operation, with no particular advantage. In my
experience roll film can be developed in Pyro on spiral reels in daylight
tanks following the same procedures used for conventional devleopers, with
this exception: agitation cycles need to be at about 30 second intervals,
and should be vigorous.
