How come BCH and BTC aren't being merge mined? Is it technically impossible?

Show me what you got, at a reasonable price, bulk offers more than welcomed. Will buy as long as the board is not black/fried beyond repair.

I posted on another thread and he came to me in PM out of the blue trying to sell me his site and not to contact him here. Very fishy but nothing lost, be safe.

Was wondering how many are out there, so far I found bitcoin cash (duh) and byteballs, any other I can claim for quick profit?
