You cannot split upload and download like that. There is no solution.

what about configuring bonding in active-backup mode, so that each router use only one link when both links are up and running?

I guess if you have your own IP space behind the two WAN circuits and do BGP on both you could aggressively prepend your own AS on the peer that gives bad download speeds so the Internet as a whole prefers the other circuit while it's up, and set a default route out the peer with good upload and a floating static to the other peer.

But with ISP IP space and no control over your prefixes in the Internet routing table I don't see how you can split upstream and downstream traffic.

huh, sorry, I thought about just two links with both ends controlled by TS %)

well, there's small chance that your 1st ISP is not blocking packets with src-address=another ISP, so you may try to do something like "/ip fi nat add chain=srcnat out-interface=isp1 action=src-nat to-addresses=isp2-address"
