I don't think it is. You have to deal with V cuts on either hull's ribs that will need to be built flat. Are you going to do a low deck, a mid dec, or a high deck? I'd low deck it in the middle and put a mid deck on the front (height of the nose seat) and add a mid deck at the rear (seat height), say as long as the width. I would not run a high deck or a total mid deck on lake water with traffic.
What are you going to power it with and as said before, what are your expectations? Anchor'd for cats, electric trolling for bass, engine trolling for walleye or stripers?
Look at the builds under the 'conversions' subforum and gather ideas. Are you going to do the work out of metal or wood, wood is heavy and you'll need lots of power and fuel to run a heavy boat?
The best suggestion is work with your dealer to get some test runs, either with customers, or the boat you plan on buying, then see what you like and don't like about it.
Food for thought, a 1648 will fish two for bass nicely, three is tight. My next one will be 1860 or wider.
