Scott's Master Bath Remodel

Hey there, hope everyone is having a great holiday....

I'm at the beginning of redoing my master bath. And I have a few questions regarding sistering joists. I have 2x10's (Doug Fir I believe) unsupported 13.5'. With that, the Deflecto calculator says I am good for ceramic tile. I am not sure what I am going to be using at this point so I want to make it the best I can. On top of the structure I will have 3/4" and 1/2" plywood followed by Ditra. I'll attach a pic so you can see what I am working with.

1. When sistering my 2x10's is it best to use 2x10 material or can I go down to say 2x6 or 2x8? I plan on sistering the full 13.5'

2. When I leave the 1/8" gap along the edge and between sheets of the subfloor can I silicone that to seal the room off from the crawlspace? It may be a while before tile gets put down.

Thanks, and again I hope everyone is having a great Holiday!
