Is there a best one lens solution for the a6700 and travel

I only really use my camera for travel, I'm a hobbyist and don't edit my photos, more because I just enjoy documenting where I go

At the moment I have 2 lenses, a Sony 18-135 which is my main stay and a Tamron 11-20 for the ultra wides.

Is there anything that can incorporate both these two lenses together.

I use a a6700 for reference.
