I don't think anything new you posted and that's why maybe people not showing interest.
Because everyone knows that Bitcoin transaction fees are slightly high compared to LTC transaction fee.
But I didn't understand why do you want to do so many conversions because you know each time you convert you need to pay exchange fee as well? Unless you want to save your money in LTC then you can do but finally, if you want to convert back to BTC or any other coins then it is not a good idea.
