Doubtfully it work since most forked coins implemented replay-protection and will make BTC transaction invalid, unless the forked Electrum wallet can fix replay-protection (changing it's SIGHASH to be precise) problem.
Read the OP, vita-b12 is using BTCP Electrum wallet and the signed Raw Tx that he will create is for Bitcoin Private chain, he just can't broadcast it due to the lack of working servers. This method will definitely work.
Replay Attack will only happen if he's using BTC Electrum and broadcast it to online BTCP broadcasters.
By the way, he never replied anyways so this might be answered already in another forums or by himself.
Or he just realized that moving them isn't gonna save his coins from being burned
