PBI Semantic Models - is Central Model Realistic?

Looking to build a central/master semantic model and then use it to have domain models build on top.

So central model would contain all master dimensions. Key transactions and KPIs (sales, finance). Domain models would additionally have domains specific KPIs and only domain specific facts or dimensions.

Is this even feasible?

Is model size still an issue even with Direct lake? Is such federated (central + domain) set up enabled?
