I wish you luck but with your use of the name Concordski I fear the worst.
The Tu-144 was considerably bigger than Concorde, had a different wing plan form (cranked delta instead of ogival), had a totally different engine layout, flew before Concorde and once the canards were fitted touched down very much slower than Concord thanks to the flapped delta effect that was then possible.
The Soviet espionage programme against Concorde was in order that they could learn all they could about Concorde and so be better prepared to compete with it round the sales table. If you feel it was in any way a copy of Concord you are ignoring the facts.
The Tu-144 programme failed not because of the aerodynamics of the airframe but because the propulsion system (intake, engine and nozzle combination) was much less efficient in a Mach 2 cruise than that fitted to Concord.
