I believe you can do it in the routing table and it will work because the more specific route will prevail. For example, you can blackhole route the whole /24 but route a /29 somewhere or even have it as a direct connect. An example would be handing out /32’s via PPPoE but blackhole routing the subnet assigned to the tower, Mikrotik then needs a route filter so OSPF doesn’t advertise all the individual /32’s.
But you are trying to have overlapping directly connected subnets. I think Mike’s right, that won’t work. Why do you want to do that?

What I am looking to do is put 172.16.2.x/29 on ether2 but I already have 172.16.2.1/24on ether1. So I don't know what I am missing here.
