I was thinking just of the idea of precalculating a local hour angle for each reflected Bris image for a days work by pocket calculator using the time sight formula or by Martelli table if going nonelectronic. The precalculations would be done anytime before the observation so as to offer immediate results upon observation (aviation style).
I think what you are talking about is a compact custom table taylored to the specific Bris sextant angles. One problem doing this is that every Bris has a unique set of angles so each Bris sextant would need it's own custom table. Lots of work :(
