table top advice

Hi all
This goes out to any of you who have built a table top to put a slot car track on. I have a 4x8 pool table and I had thought originally that I would get a ping pong table conversion top to put on top of the pool table. It would measure 9x5. I know that is a bit small for the carrera track I would like to put on it, so I thought I might build my own 10x6 table top. I was considering the following for construction. I would use 2- 1x4x10 for the length and 6- 1x4x6 cut t0 58" , so that plus the 2" of the side pieces would equal a total of 60". I was then going to use 4- 4x8 sheets of luan under layment , cut to the appropriate sizes to put on both the top and the bottom of the 1x4's. I found a place where I can buy 1/4" neoprene foam that I would put on the bottom of the table to it would sit on the pool table and protect the wood rails. so my question for those whose carpentry skills may be better than mine: will the 1x4's set up the way I have described be sturdy enough to support the the luan underlayment board? My goal is to have 10x6 surface area but it must be movable, so I want to keep it as light as possible because it will take 2 people to put it in place on the pool table. I could even build it with 1x3's but again I don't know if it will be sturdy enough to support its own weight. I hope that what I am asking makes sense and I look forward to any comments and suggestions you all may have. Thanks Tom
