You can indeed. You have a few options you would want to consider.
First I would recommend that you run the 387 in the latest 8.6. There were changes to the default 60Ghz behavior in 8.6 that makes it much more stable and secure that could not be pulled back in to 8.5.
Also, while you CAN pull in the 387 into the same VC as the other instant APs on the network, you may want to keep them separate so that you can fully manage the bridge separately from the rest, and also prevents you from having to upgrade both indoor APs and the bridges when code upgrades occur.
From there, you can absolutely carry native and trunked VLANs over the mesh PtP. Note that max distance for the AP-387s is 400m. They are configured exactly like other Instant AP mesh devices which you can find setup in the user guide or multiple posts here on Community.
