2x10 and 1x10 compatibility - help?

Supposing you were building a bike which has ISCG mounts and you wanted to run a 2x10 (22-32) most of the time with a chain device and bash, but wanted to temporarily convert it to a 1x10 (32) with an upper chain guide etc. for an alps trip. Is it an easy thing to do and change over and what would be the most suitable groupset to build this off and the best chain device etc?
