Can i simulate trezor seed recovery on an offline computer?

I use trezor for bitcoins and litecoins. How can i verify that i get the same private keys and addresses from the initial seed?I want to run a program or a code on an offline computer, that takes as input the 24 words seed, and returns the following:the seed (in a number format)the private addresses of wallets (litecoin, bitcoin)the public addresses of walletsThe point is: i want to be 100% sure that i can recover all of these using just the 24-words trezor seed, and that electrum-ltc really shows the right addresses. Also, i dont want to buy another trezor just in case this one gets stolen, and i have to recover my btc and ltc fast. via /r/Bitcoin http://bit.ly/1qRraKy
