No it’s not
As it needs another cassette and an other pair of discs. Swapping tyres with tubes is way quicker anyway and I have three sets of tyres as said. So three pairs of wheel 3 cassettes and 6 discs. Really? Why stop there, 3 bikes?
As it happens I do now have a spare set of wheels as the stock ones are chocolate, but that’s a whole other rant and I won’t be using those agsin
No need for three cassettes, it's about a minute to swap a cassette from one hub to another. Running three cassettes would not work well unless your are swapping wheels very regularly, as the cassette, chain and chainring wear together and using a less worn cassette with more worn chain will usually cause shifting issues and skipping.
Arguably two bikes may not be a bad idea, one for riding on the road (imagine if there was a genre of bikes specifically for this!!) and a mountain bike you swap the tyres on to suit the season.
