Torrance,
If you enable client access on the backhaul link of the 1552, then you can have non-mesh-backhaul associations on that radio. I have done this successfully with Cisco 1410 outdoor bridges. The Yagi antenna is not a functional software aspect, it is a hardware and physical aspect of the way the energy from your 352s is focused and radiated.
Aren’t the 350 series APs 2.4GHz only? 1552s are .11a-side (5GHz) backhaul only. There is support for .11b-side backhaul in the slightly older 1522, configurable from the CLI, but this is, of course, not recommended because of the numerous issues with limited spectrum, congestion, etc.
If you want a less expensive spoke node, you might consider a 1262 in an weather-rated enclosure. You don’t necessarily need to go all the way up to a 1552 on your spokes in order to make the bridging work.
Alternatively, if you really have to keep your old 352s on as spokes, you can do an autonomous bridge at your hub using P2MP bridging on the 2.4GHz radio. 1500 series APs are lightweight only, so you’d need to look at a 1240, 1260 or 3500 for something like that.
