I get what you mean here but I don't think I'm ready to go BB yet. On the other hand is 1" of substrate just going to become a crud collector? Would a remote DSB help?

A remote DSB won't help with debris in the main just used to help check the nitrates.

Sand in the main can be kept clean by good flow so crud is in suspension and carried to the overflow. Also if running a shallow bed, vacuuming isn't a issue (as opposed to disturbing a DSB).

I have a 75g with 6000gph flow, and I get plenty of crud settling. Good flow will not prevent detritus buildup in the sandbed.

You won't be able to silicone the starboard to the bottom properly from what I've read. Silicone doesn't like plastic much over the long run.

Anyway, another option is just to spraypaint the bottom of the tank white.
