In the past, I was an trained on aviation corrosion control in a marine environment, so I can give you a few tips...
Bikes and airplanes are similar in that they have a variety of fasteners and components made from different metals and alloys. Regular cleaning, inspection and lubrication is going to be your best friend. If it very unlikely you are going to be able to find a buy it and forget it type of bicycle.
Aluminum does not rust, but it corrodes just the same. Especially in contact with other metals (galvanic corrosion). It's going to turn into white flakey powder which will eventually just crumble away.
IMO, galvanic/dissimilar metal corrosion is going to be your biggest problem on a bicycle in a marine env (it certainly was for A/C). Ti and steel or stainless steel touching Al are going to be your pain points. Disassemble and lubricate where everything touches.
We used a variety of lubricants with mil spec numbers, but the stuff we sprayed on hinged and and bare dings smelled and feels exactly like Frame Saver. I suspect it is the same product just repackaged.
I would suggest putting some master links on the chain and just bagging it in a zip lock for storage. Probably much easier than trying to keep it from rusting.

The other question I don't have an answer to would be Bagging the whole bike and using a moisture absorb material (kitty litter) to keep the bike dry.

6061 Aluminum is a marine grade and should have reasonably good corrosion resistance.
7xxx grade aluminum can be lighter and stronger, but with worse corrosion.
