Could be. Though must admit I am doing kind of the same thing only on a much, much smaller scale.
Agree, BTC tx fees are ridiculous nowadays so if your doing a lot of transactions you might as well make use of BCH then settle your position in BTC. Also, there are days when even though BTC is so high, it is sometimes more plofitable mining BCH as the difficulty has remained fairly stable.
Already it is on work from in next hard fork time bro. Even the block size will be increased at the time. Then you can find the bitcoin transaction half of the time lower than what you are seeing now.
Since some of the wallet can be modified the bitcoin transaction fees to some how.
