guide to setup my home network ?

I want to set my Home Network; the picture summarizes the current map of the house, I want to make the Covr Wireless internet from the PPPOE coming into the Mikrotik(Wireless from ISP2) the Dlink router Takes Internet from the ADSL connection and gives DHCP IP to the Mikrotik and the cable to apartment 2 take internet from the ADSL that’s the scenario that I want can that be done? and How?
another scenario I was thinking is merging both ISPs using the Mikrotik and Load Balancer but I don’t know if that can be done if the 2 ISPs are different?
My plan is to take the Fastest Internet for Myself and give the family the regular internet since my work demands stronger network speed and uninterrupted connection.
