COALESCE or not for Lan hosts?

We have different vendors in our environment and they can use different parameters for some things.
When we first started with vendor 1, the Lan clients were fetched with the parameter “Device.Hosts.Host” so we made a “Lan Clients” section for that model that presented us with a table of the clients and their IP’s and all that stuff.

Vendor 2 uses “InternetGatewayDevice.LANDevice.1.Hosts.Host” for the Lan Clients and they can’t be presented within the same table as Vendor 1 clients.

Is it risky for performance/ database to use COALESCE(Device.Hosts.Host, InternetGatewayDevice.LANDevice.1.Hosts.Host)
for the “ui.device.3.parameter” ?
