the 1x stuff is just a fad, once people realize, after they spent the damn money to get one, that they have gearing limitations. I too think it's a silly idea. I saw a 1x touring bike?! I guess that's great if you won't be doing carrying a lot of camping gear and not going up mountain roads.
As far as mounting more water bottle cages, don't use the idea of going with a hose clamp and clamping a cage to the frame that way, you have to tighten the bolts too much which will crush the CF frame. So the best thing to use without resorting to clamps is using the Wolf Tooth Components B-Rad double bottle cage adapter, this will make it so you can carry two bottles with just your single mount and it's relatively inexpensive at just $25, see:

Pannier wise you're screwed! They do make a mount that takes the place of your skewer, but I ran into a guy that used one of those and his broke after only around 300 miles into his trip! I happened to be in my pickup truck so I gave him a lift to the bike shop, but it's something I wouldn't trust. so you're left with attaching frame bags which a lot of riders do but it does increase your center of gravity vs panniers. Here is website showing examples of bike bags, keep in mind certain ones won't work like that bag that fits inside and takes up your frame triangle area because you have water bottles you need to carry; anyway see this:

Fenders you would have to use clip on style and they can rattle and move out of position, but those are the only choice you have. Here is a site that shows a few different kinds, once you chose a model check the review on it to make sure it's as good as you hope.

You can make that bike work but for touring you will need to go into more ultralight gear which costs more money but the stuff does work. I tour also but I have a regular touring bike and I use panniers so my cost for camping gear doesn't have to be as high because I don't have to find the lightest stuff I can find. If you do decide to tour on that bike you need to buy the bare bones minimum stuff, then go someplace locally and camp and see what you need from there, once you've done that go a little further and see what you need then, this way you don't overspend for stuff that when you do go decide **** I didn't need that and thus spent money for no reason.
ALSO, if you shop at REI, which can be a bit more expensive than a few other places but if for some reason you don't like something you bought, even after you've used it, you can return it for something else, of course you do need to become a member to get this privilege but it's worth it. Once you're a member you'll get special notices of sales and can save a lot of money doing that. For example I'm a member and they sent in my an e-mail of a sale going on for tents, I got a Marmot tungsten 2 that retailed for $200 for just $128. My friend is also a member he bought a $350 tent for $260, it leaked on the first trial, he sent it back and REI upgraded him to the next level without any additional charge. Anyway REI is a good place to get more expensive stuff, some small cheaper camping stuff you get from WALMART! I got stuff from there and had no issues, anyways if you want to know more about what I got for cheap at Walmart just let me know, there is other stuff too on Amazon that you can find dirt cheap that works really good like my $11 stove with a built in ignitor that works fantastically, as good as my friend's who spent 8 times more than mine did! Just let me know if you're interested in more info.
