Some time back I did the US Missouri. Started it in the 1990's and after about 10 to 20 hours work realised I needed so practice and I wanted to do it as a water-line model with Photo-Etch railings etc. so back in the box it went. Fast forward ten years or more. First thing I would advice is make a display case for the model that way it can be safly be put away out of harms way and it reains dust free.
The next few months the construction was more or less done and the painting completed. The main superstructures were left free to make the rigging easier by pulling the rigging from the underside and then gluing in place. If using PE don't use all the parts supplied as often the plastic parts or better as PE can be very 2 dimentional. Using PE realings really makes the biggest improvement and really isn't that diffecult, just tack it in a few places with CA glue then run som diluted PVA along the join, it's surprizing how strong it becomes.
Once I'd restarted the kit it took about 6 months but that was working on and off and I think I actually made another kit for a change of pace in that 6 months. Making something like you're thinking off is going to require quite a commitment in time and concentration but if you take your time and do it logically it is well worth the effort once finished. That case I made for mine was the best thing I could have done as it was a real life saver.
Good luck with you're 350 battleship.
