New Crankset for my Carrera Subway

[tweed]

I have a Carrera Subway with a Suntour XCT 8 speed triple crankset. I would like to do some full loaded touring on it and as such would like to swap the crankset for a 42/32/22. Would anyone know if this would be suitable...

Or could you recommend something else?
Many thanks
