Using Instanced Static Mesh Component with one instance instead of Static Mesh Component

I need custom component inheriting Static Mesh Component but it is possible for only Instanced Static Mesh Component by right-click -> Blueprint Class -> InstancedStaticMeshComponent. The newly created component will only be used as Movable and transformed by blueprint timeline. Do you think I can use ISMC with one instance instead of an actual SMC without any problems?
I saw this but after testing, those limitations aren’t true anymore. Are there any other differences between ISMC and SMC? Thanks.

Bump. I still really need to know this, it is the final piece of the thing I’m working on :).
