If I build Mt122 rectangular and not trapezoidal and so doing increase the chamber volume but not the horn will this impact on the performance of the horn

I've not built the 122 yet, only the 102, and in that case, a small rear chamber is best, Rog recommends an even narrower gap (hence rear chamber volume) than in the drawing, in the FAQ.

I had intended to build single MT122 like Doms; his dont appear to be
trapezoidal maybe the solution is the original rear chamber (as in the plans) within a rectangular cab

Mine have a rear chamber as per the plans.
