Definitely! She's a really cool Pokémon. I like her speed wise and she would be a decent fighter.
Froslass is a good pokemon, while its attack and special attack may not be the best (sometimes forget she has the same atk and sp atk stat) her speed and not so bad movepool does work out in most cases
Also, can I just say that Purugly and Stoutland are some of the most underrated Normal types out there? You have Purugly who's as fast as Mega Lucario (base 112 speed) and has a wide range of moves from Sucker Punch, Play Rough, Super Fang, Return, U Turn, etc. Plus its hidden ability Defiant can really give a middle finger to intimidate users.
Now with Stoutland, starting off with its 3 great abilities Sand Rush (perfect for sand teams), Intimidate (self explanitory), and Scrappy (allowing it to hit ghost types), unlike Purugly, it hits much harder and its abilities all give it a fair amount of usefullness. It can be a hard hitter with its base 110 attack, may be a bit bulky with intimidate to help out its "ok" defenses, and like I mentioned with Sand Rush perfect for sand teams which helps out its base 80 speed. I've seen Scarfed, Sand Rush, After You Stoutlands paired with Tyranitar in double battles to help the slowest of TTars spam Rock Slides and destroyed teams, really, how is Stoutland not used that much?
