Depends on skill level of fabricator/ carpenter/ builder. Make the joinery an on purpose carpentry joinery detail. Thats how quality furniture is supposed to be built. Joinery part of the beauty. Will look for example for you. Finger joints and other joinery is beautiful. Will cost though! I would design top differently than to try and look like one continuous wood top. That is not reflecting the authenticity of the materials. Ultimately makes for a quality piece of furniture to design in alignment with material characteristics and authentic strength and limitations.

Here we have picture of ugly support column finished in wood with finger joints or overlapping joints at corners. Ugly column now pretty interesting or at least we don't mind it in the space.
