Hey it won’t be worth the hassle.
Yes, it will work. But not smoothly. The indexing of the 8 speed Claris will not match exactly with the Tourney groupset on the RC 100.
Either ride the bike as is or buy a bike with better components. Wouldn’t even recommend upgrading to Claris. Again not worth the hassle/ money!
